bitmap-fallback: Support converting all pixel format types _cogl_bitmap_fallback_convert now supports converting to and from all of the pixel formats, except it continues to preserve the premult status of the original bitmap. The pixels are unpacked into a temporary buffer that is either 8-bits per component or 16-bits per component RGBA depending on whether the destination format is going to use more than 8 bits per component (eg RGBA_1010102). The packing and unpacking code is stored in a separate header which is included twice to generate the functions needed for both sizes of unpacked data. The hope is that when converting between two formats that are both 8-bit sized, such as swizzling between BGRA and RGBA, then the multiplications and divisions in the code will be optimized out and it shouldn't be too inefficient. Previously the inner switch statement to decide which conversion to use only operated on one pixel at a time so it was probably relatively slow. Reviewed-by: Robert Bragg <robert@linux.intel.com>

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.

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.

framebuffer: Support texture based depth buffers This commit introduces some new framebuffer api to be able to enable texture based depth buffers for a framebuffer (currently only supported for offscreen framebuffers) and once allocated to be able to retrieve the depth buffer as a texture for further usage, say, to implement shadow mapping. The API works as follow: * Before the framebuffer is allocated, you can request that a depth texture is created with cogl_framebuffer_set_depth_texture_enabled() * cogl_framebuffer_get_depth_texture() can then be used to grab a CoglTexture once the framebuffer has been allocated.

The pixels are unpacked into a temporary buffer that is either 8-bits per component or 16-bits per component RGBA depending on whether the destination format is going to use more than 8 bits per component (eg RGBA_1010102).

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.

framebuffer: Support texture based depth buffers This commit introduces some new framebuffer api to be able to enable texture based depth buffers for a framebuffer (currently only supported for offscreen framebuffers) and once allocated to be able to retrieve the depth buffer as a texture for further usage, say, to implement shadow mapping. The API works as follow: * Before the framebuffer is allocated, you can request that a depth texture is created with cogl_framebuffer_set_depth_texture_enabled() * cogl_framebuffer_get_depth_texture() can then be used to grab a CoglTexture once the framebuffer has been allocated.
