Removes all remaining use of CoglHandle Removing CoglHandle has been an on going goal for quite a long time now and finally this patch removes the last remaining uses of the CoglHandle type and the cogl_handle_ apis. Since the big remaining users of CoglHandle were the cogl_program_ and cogl_shader_ apis which have replaced with the CoglSnippets api this patch removes both of these apis. Reviewed-by: Neil Roberts <neil@linux.intel.com> (cherry picked from commit 6ed3aaf4be21d605a1ed3176b3ea825933f85cf0) Since the original patch was done after removing deprecated API this back ported patch doesn't affect deprecated API and so actually this cherry-pick doesn't remove all remaining use of CoglHandle as it did for the master branch of Cogl.

cogl-bitmap: Encapsulate the CoglBitmap even internally The CoglBitmap struct is now only defined within cogl-bitmap.c so that all of its members can now only be accessed with accessor functions. To get to the data pointer for the bitmap image you must first call _cogl_bitmap_map and later call _cogl_bitmap_unmap. The map function takes the same arguments as cogl_pixel_array_map so that eventually we can make a bitmap optionally internally divert to a pixel array. There is a _cogl_bitmap_new_from_data function which constructs a new bitmap object and takes ownership of the data pointer. The function gets passed a destroy callback which gets called when the bitmap is freed. This is similar to how gdk_pixbuf_new_from_data works. Alternatively NULL can be passed for the destroy function which means that the caller will manage the life of the pointer (but must guarantee that it stays alive at least until the bitmap is freed). This mechanism is used instead of the old approach of creating a CoglBitmap struct on the stack and manually filling in the members. It could also later be used to create a CoglBitmap that owns a GdkPixbuf ref so that we don't necessarily have to copy the GdkPixbuf data when converting to a bitmap. There is also _cogl_bitmap_new_shared. This creates a bitmap using a reference to another CoglBitmap for the data. This is a bit of a hack but it is needed by the atlas texture backend which wants to divert the set_region virtual to another texture but it needs to override the format of the bitmap to ignore the premult flag.

bitmap: Adds cogl_android_bitmap_new_from_asset() This adds some android specific api for creating a CoglBitmap from an Android asset. As part of the work it also seemed like a good time to change the internal bitmap constructors to take an explicit CoglContext argument and so the public cogl_bitmap_new_from_file() api was also changed accordingly to take a CoglContext pointer as the first argument. Reviewed-by: Neil Roberts <neil@linux.intel.com> (cherry picked from commit 099d6d1b505b55bbd09c50d081deb41ab5764e19) Since we aren't able to break APIs on the 1.12 branch this cherry-pick skips the change to cogl_bitmap_new_from_file()

Allow npot Texture2D creation with only basic npot support Cogl has feature flags for basic npot texture support and then separate flags for npot + repeat and npot + mipmap. If those three features are available then there is a feature for full-npot support too for convenience. The cogl_texture_2d_new_ constructors were checking for full npot support and failing if not available but since we expose the fine grained features to the user the user should be able to check the limitations of npot textures and still choose to allocate them. _cogl_texture_2d_can_create() now only checks for basic npot support when creating a npot texture. Since this change also affects the automagic cogl_texture_ constructors they now check for basic npot + mipmap support before considering using a Texture2D. Notably the cogl_texture_ constructors will try constructing a Texture2D even if we don't have npot + repeat support since the alternative is a sliced texture which will need manual repeating anyway. Accordingly the Texture2D::can_hardware_repeat and ::transform_quad_coords_to_gl vfuncs have been made aware of the npot + repeat feature flag.

Allow propogation of OOM errors to apps This allows apps to catch out-of-memory errors when allocating textures. Textures can be pretty huge at times and so it's quite possible for an application to try and allocate more memory than is available. It's also very possible that the application can take some action in response to reduce memory pressure (such as freeing up texture caches perhaps) so we shouldn't just automatically abort like we do for trivial heap allocations. These public functions now take a CoglError argument so applications can catch out of memory errors: cogl_buffer_map cogl_buffer_map_range cogl_buffer_set_data cogl_framebuffer_read_pixels_into_bitmap cogl_pixel_buffer_new cogl_texture_new_from_data cogl_texture_new_from_bitmap Note: we've been quite conservative with how many apis we let throw OOM CoglErrors since we don't really want to put a burdon on developers to be checking for errors with every cogl api call. So long as there is some lower level api for apps to use that let them catch OOM errors for everything necessary that's enough and we don't have to make more convenient apis more awkward to use. The main focus is on bitmaps and texture allocations since they can be particularly large and prone to failing. A new cogl_attribute_buffer_new_with_size() function has been added in case developers need to catch OOM errors when allocating attribute buffers whereby they can first use _buffer_new_with_size() (which doesn't take a CoglError) followed by cogl_buffer_set_data() which will lazily allocate the buffer storage and report OOM errors. Reviewed-by: Neil Roberts <neil@linux.intel.com> (cherry picked from commit f7735e141ad537a253b02afa2a8238f96340b978) Note: since we can't break the API for Cogl 1.x then actually the main purpose of cherry picking this patch is to keep in-line with changes on the master branch so that we can easily cherry-pick patches. All the api changes relating stable apis released on the 1.12 branch have been reverted as part of cherry-picking this patch so this most just applies all the internal plumbing changes that enable us to correctly propagate OOM errors.

bitmap: Remove the split between 'image library' and 'fallback' Previously the bitmap code was setup so that there could be an image library used to convert between formats and then some 'fallback' code when the image library can't handle the conversion. However there was never any implementation of the conversion in the image library so the fallback was always used. I don't think this split really makes sense so this patch renames cogl-bitmap-fallback to cogl-bitmap-conversion and removes the stub conversion functions in the image library.

texture: remove _cogl_texture_prepare_for_upload This removes the gl centric _cogl_texture_prepare_for_upload api from cogl-texture.c and instead adds a _cogl_bitmap_convert_for_upload() api which everything now uses instead. GL specific code that needed the gl internal/format/type enums returned by _cogl_texture_prepare_for_upload now use ->pixel_format_to_gl directly. Since there was a special case optimization in cogl_texture_new_from_file that aimed to avoid copying the temporary bitmap that's created for the given file and allow conversions to happen in-place the new _cogl_bitmap_convert_for_upload() api supports converting in place depending on a 'can_convert_in_place' argument.

Switch use of primitive glib types to c99 equivalents The coding style has for a long time said to avoid using redundant glib data types such as gint or gchar etc because we feel that they make the code look unnecessarily foreign to developers coming from outside of the Gnome developer community.

Textures can be pretty huge at times and so it's quite possible for an application to try and allocate more memory than is available. It's also very possible that the application can take some action in response to reduce memory pressure (such as freeing up texture caches perhaps) so we shouldn't just automatically abort like we do for trivial heap allocations.

So long as there is some lower level api for apps to use that let them catch OOM errors for everything necessary that's enough and we don't have to make more convenient apis more awkward to use. The main focus is on bitmaps and texture allocations since they can be particularly large and prone to failing. A new cogl_attribute_buffer_new_with_size() function has been added in case developers need to catch OOM errors when allocating attribute buffers whereby they can first use _buffer_new_with_size() (which doesn't take a CoglError) followed by cogl_buffer_set_data() which will lazily allocate the buffer storage and report OOM errors.

cogl-bitmap: Encapsulate the CoglBitmap even internally The CoglBitmap struct is now only defined within cogl-bitmap.c so that all of its members can now only be accessed with accessor functions. To get to the data pointer for the bitmap image you must first call _cogl_bitmap_map and later call _cogl_bitmap_unmap. The map function takes the same arguments as cogl_pixel_array_map so that eventually we can make a bitmap optionally internally divert to a pixel array. There is a _cogl_bitmap_new_from_data function which constructs a new bitmap object and takes ownership of the data pointer. The function gets passed a destroy callback which gets called when the bitmap is freed. This is similar to how gdk_pixbuf_new_from_data works. Alternatively NULL can be passed for the destroy function which means that the caller will manage the life of the pointer (but must guarantee that it stays alive at least until the bitmap is freed). This mechanism is used instead of the old approach of creating a CoglBitmap struct on the stack and manually filling in the members. It could also later be used to create a CoglBitmap that owns a GdkPixbuf ref so that we don't necessarily have to copy the GdkPixbuf data when converting to a bitmap. There is also _cogl_bitmap_new_shared. This creates a bitmap using a reference to another CoglBitmap for the data. This is a bit of a hack but it is needed by the atlas texture backend which wants to divert the set_region virtual to another texture but it needs to override the format of the bitmap to ignore the premult flag.

Adds CoglError api Although we use GLib internally in Cogl we would rather not leak GLib api through Cogl's own api, except through explicitly namespaced cogl_glib_ / cogl_gtype_ feature apis. One of the benefits we see to not leaking GLib through Cogl's public API is that documentation for Cogl won't need to first introduce the Glib API to newcomers, thus hopefully lowering the barrier to learning Cogl. This patch provides a Cogl specific typedef for reporting runtime errors which by no coincidence matches the typedef for GError exactly. If Cogl is built with --enable-glib (default) then developers can even safely assume that a CoglError is a GError under the hood. This patch also enforces a consistent policy for when NULL is passed as an error argument and an error is thrown. In this case we log the error and abort the application, instead of silently ignoring it. In common cases where nothing has been implemented to handle a particular error and/or where applications are just printing the error and aborting themselves then this saves some typing. This also seems more consistent with language based exceptions which usually cause a program to abort if they are not explicitly caught (which passing a non-NULL error signifies in this case) Since this policy for NULL error pointers is stricter than the standard GError convention, there is a clear note in the documentation to warn developers that are used to using the GError api. Reviewed-by: Neil Roberts <neil@linux.intel.com> (cherry picked from commit b068d5ea09ab32c37e8c965fc8582c85d1b2db46) Note: Since we can't change the Cogl 1.x api the patch was changed to not rename _error_quark() functions to be _error_domain() functions and although it's a bit ugly, instead of providing our own CoglError type that's compatible with GError we simply #define CoglError to GError unless Cogl is built with glib disabled. Note: this patch does technically introduce an API break since it drops the cogl_error_get_type() symbol generated by glib-mkenum (Since the CoglError enum was replaced by a CoglSystemError enum) but for now we are assuming that this will not affect anyone currently using the Cogl API. If this does turn out to be a problem in practice then we would be able to fix this my manually copying an implementation of cogl_error_get_type() generated by glib-mkenum into a compatibility source file and we could also define the original COGL_ERROR_ enums for compatibility too. Note: another minor concern with cherry-picking this patch to the 1.14 branch is that an api scanner would be lead to believe that some APIs have changed, and for example the gobject-introspection parser which understands the semantics of GError will not understand the semantics of CoglError. We expect most people that have tried to use gobject-introspection with Cogl already understand though that it is not well suited to generating bindings of the Cogl api anyway and we aren't aware or anyone depending on such bindings for apis involving GErrors. (GnomeShell only makes very-very minimal use of Cogl via the gjs bindings for the cogl_rectangle and cogl_color apis.) The main reason we have cherry-picked this patch to the 1.14 branch even given the above concerns is that without it it would become very awkward for us to cherry-pick other beneficial patches from master.

cogl-texture: Don't use the source rowstride if we have to copy bitmap If we have to copy the bitmap to do the premultiplication then we were previously using the rowstride of the source image as the rowstride for the new image. This is wasteful if the source image is a subregion of a larger image which would make it use a large rowstride. If we have to copy the data anyway we might as well compact it to the smallest rowstride. This also prevents the copy from reading past the end of the last row of pixels. An internal function called _cogl_bitmap_copy has been added to do the copy. It creates a new bitmap with the smallest possible rowstride rounded up the nearest multiple of 4 bytes. There may be other places in Cogl that are currently assuming we can read height*rowstride of the source buffer so they may want to take advantage of this function too. http://bugzilla.clutter-project.org/show_bug.cgi?id=2491

Switch use of primitive glib types to c99 equivalents The coding style has for a long time said to avoid using redundant glib data types such as gint or gchar etc because we feel that they make the code look unnecessarily foreign to developers coming from outside of the Gnome developer community. Note: When we tried to find the historical rationale for the types we just found that they were apparently only added for consistent syntax highlighting which didn't seem that compelling. Up until now we have been continuing to use some of the platform specific type such as gint{8,16,32,64} and gsize but this patch switches us over to using the standard c99 equivalents instead so we can further ensure that our code looks familiar to the widest range of C developers who might potentially contribute to Cogl. So instead of using the gint{8,16,32,64} and guint{8,16,32,64} types this switches all Cogl code to instead use the int{8,16,32,64}_t and uint{8,16,32,64}_t c99 types instead. Instead of gsize we now use size_t For now we are not going to use the c99 _Bool type and instead we have introduced a new CoglBool type to use instead of gboolean.

CoglBool
cogl: improves header and coding style consistency We've had complaints that our Cogl code/headers are a bit "special" so this is a first pass at tidying things up by giving them some consistency. These changes are all consistent with how new code in Cogl is being written, but the style isn't consistently applied across all code yet. There are two parts to this patch; but since each one required a large amount of effort to maintain tidy indenting it made sense to combine the changes to reduce the time spent re indenting the same lines. The first change is to use a consistent style for declaring function prototypes in headers. Cogl headers now consistently use this style for prototypes: return_type cogl_function_name (CoglType arg0, CoglType arg1); Not everyone likes this style, but it seems that most of the currently active Cogl developers agree on it. The second change is to constrain the use of redundant glib data types in Cogl. Uses of gint, guint, gfloat, glong, gulong and gchar have all been replaced with int, unsigned int, float, long, unsigned long and char respectively. When talking about pixel data; use of guchar has been replaced with guint8, otherwise unsigned char can be used. The glib types that we continue to use for portability are gboolean, gint{8,16,32,64}, guint{8,16,32,64} and gsize. The general intention is that Cogl should look palatable to the widest range of C programmers including those outside the Gnome community so - especially for the public API - we want to minimize the number of foreign looking typedefs.

cogl-bitmap: Encapsulate the CoglBitmap even internally The CoglBitmap struct is now only defined within cogl-bitmap.c so that all of its members can now only be accessed with accessor functions. To get to the data pointer for the bitmap image you must first call _cogl_bitmap_map and later call _cogl_bitmap_unmap. The map function takes the same arguments as cogl_pixel_array_map so that eventually we can make a bitmap optionally internally divert to a pixel array. There is a _cogl_bitmap_new_from_data function which constructs a new bitmap object and takes ownership of the data pointer. The function gets passed a destroy callback which gets called when the bitmap is freed. This is similar to how gdk_pixbuf_new_from_data works. Alternatively NULL can be passed for the destroy function which means that the caller will manage the life of the pointer (but must guarantee that it stays alive at least until the bitmap is freed). This mechanism is used instead of the old approach of creating a CoglBitmap struct on the stack and manually filling in the members. It could also later be used to create a CoglBitmap that owns a GdkPixbuf ref so that we don't necessarily have to copy the GdkPixbuf data when converting to a bitmap. There is also _cogl_bitmap_new_shared. This creates a bitmap using a reference to another CoglBitmap for the data. This is a bit of a hack but it is needed by the atlas texture backend which wants to divert the set_region virtual to another texture but it needs to override the format of the bitmap to ignore the premult flag.

cogl: Don't assume that CoglBitmaps are allocated to height*rowstride Cogl no longer has any code that assumes the buffer in a CoglBitmap is allocated to the full size of height*rowstride. We should comment that this is the case so that we remember to keep it that way. This is important for cogl_texture_new_from_data because the application may have created the data from a sub-region of a larger image and in that case it's not safe to read the full rowstride of the last row when the sub region contains the last row of the larger image. http://bugzilla.clutter-project.org/show_bug.cgi?id=2491

the rowstride of the last row. This will be the case if the user
