cogl: Add a CoglTexture2D backend This is an optimised version of CoglTexture2DSliced that always deals with a single texture and always uses the GL_TEXTURE_2D target. cogl_texture_new_from_bitmap now tries to use this backend first. If it can't create a texture with that size then it falls back the sliced backend. cogl_texture_upload_data_prepare has been split into two functions because the sliced backend needs to know the real internal format before the conversion is performed. Otherwise the converted bitmap will be wasted if the backend can't support the size.

Fix the header guards for cogl-texture-2d{,-private}.h The header guard for cogl-texture-2d-private.h was __COGL_TEXTURE_2D_H. This would conflict with the header guard for cogl-texture-2d.h except there a small typo ('TEXURE') so that it was subtly different. This fixes them both to make more sense.

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.

#include "cogl-object-private.h"
cogl: rename CoglMaterial -> CoglPipeline This applies an API naming change that's been deliberated over for a while now which is to rename CoglMaterial to CoglPipeline. For now the new pipeline API is marked as experimental and public headers continue to talk about materials not pipelines. The CoglMaterial API is now maintained in terms of the cogl_pipeline API internally. Currently this API is targeting Cogl 2.0 so we will have time to integrate it properly with other upcoming Cogl 2.0 work. The basic reasons for the rename are: - That the term "material" implies to many people that they are constrained to fragment processing; perhaps as some kind of high-level texture abstraction. - In Clutter they get exposed by ClutterTexture actors which may be re-inforcing this misconception. - When comparing how other frameworks use the term material, a material sometimes describes a multi-pass fragment processing technique which isn't the case in Cogl. - In code, "CoglPipeline" will hopefully be a much more self documenting summary of what these objects represent; a full GPU pipeline configuration including, for example, vertex processing, fragment processing and blending. - When considering the API documentation story, at some point we need a document introducing developers to how the "GPU pipeline" works so it should become intuitive that CoglPipeline maps back to that description of the GPU pipeline. - This is consistent in terminology and concept to OpenGL 4's new pipeline object which is a container for program objects. Note: The cogl-material.[ch] files have been renamed to cogl-material-compat.[ch] because otherwise git doesn't seem to treat the change as a moving the old cogl-material.c->cogl-pipeline.c and so we loose all our git-blame history.

Actually we already do a good job of listing the specific headers we depend on in each of the .c files we have so mostly this patch just strip out the redundant includes for cogl.h with a few fixups where that broke the build.

Allow lazy texture storage allocation Consistent with how we lazily allocate framebuffers this patch allows us to instantiate textures but still specify constraints and requirements before allocating storage so that we can be sure to allocate the most appropriate/efficient storage. This adds a cogl_texture_allocate() function that is analogous to cogl_framebuffer_allocate() which can optionally be called to explicitly allocate storage and catch any errors. If this function isn't used explicitly then Cogl will implicitly ensure textures are allocated before the storage is needed. It is generally recommended to rely on lazy storage allocation or at least perform explicit allocation as late as possible so Cogl can be fully informed about the best way to allocate storage. Reviewed-by: Neil Roberts <neil@linux.intel.com> (cherry picked from commit 1fa7c0f10a8a03043e3c75cb079a49625df098b7) Note: This reverts the cogl_texture_rectangle_new_with_size API change that dropped the CoglError argument and keeps the semantics of allocating the texture immediately. This is because Mutter currently uses this API so we will probably look at updating this later once we have a corresponding Mutter patch prepared. The other API changes were kept since they only affected experimental api.

Add a GL_GENERATE_MIPMAP fallback to the texture 2d and 3d backends The CoglTexture2DSliced backend has a fallback for when the framebuffer extension is missing so it's not possible to use glGenerateMipmap. This involves keeping a copy of the upper-left pixel of the tex image so that we can temporarily enable GL_GENERATE_MIPMAP on the texture object and do a sub texture update by reuploading the contents of the first pixel. This patch copies that mechanism to the 2D and 3D backends. The CoglTexturePixel structure which was previously internal to the sliced backend has been moved to cogl-texture-private.h so that it can be shared.

remove internal_format and redundant error arguments Texture allocation is now consistently handled lazily such that the internal format can now be controlled using cogl_texture_set_components() and cogl_texture_set_premultiplied() before allocating the texture with cogl_texture_allocate(). This means that the internal_format arguments to texture constructors are now redundant and since most of the texture constructors now can't ever fail the error arguments are also redundant. This now means we no longer use CoglPixelFormat in the public api for describing the internal format of textures which had been bad solution originally due to how specific CoglPixelFormat is which is missleading when we don't support such explicit control over the internal format.

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.

introduce texture loaders to make allocations lazy This introduces the internal idea of texture loaders that track the state for loading and allocating a texture. This defers a lot more work until the texture is allocated. There are several intentions to this change: - provides a means for extending how textures are allocated without requiring all the parameters to be supplied in a single _texture_new() function call. - allow us to remove the internal_format argument from all _texture_new() apis since using CoglPixelFormat is bad way of expressing the internal format constraints because it is too specific. For now the internal_format arguments haven't actually been removed but this patch does introduce replacement apis for controlling the internal format: cogl_texture_set_components() lets you specify what components your texture needs when it is allocated. cogl_texture_set_premultiplied() lets you specify whether a texture data should be interpreted as premultiplied or not. - Enable us to support asynchronous texture loading + allocation in the future. Of note, the _new_from_data() texture constructors all continue to allocate textures immediately so that existing code doesn't need to be adapted to manage the lifetime of the data being uploaded.

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.

Fix the header guards for cogl-texture-2d{,-private}.h The header guard for cogl-texture-2d-private.h was __COGL_TEXTURE_2D_H. This would conflict with the header guard for cogl-texture-2d.h except there a small typo ('TEXURE') so that it was subtly different. This fixes them both to make more sense.
