texture: split out high-level texture constructors This splits out the very high level texture constructors that may internally construct one of several types of lower level texture due to various constraints. This also updates the prototypes for these constructors to take an explicit context pointer and return a CoglError consistent with other texture constructors.

CoglTexture *
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.

Expose CoglAtlasTexture api This exposes the CoglAtlasTexture api, making the following public: cogl_atlas_texture_new_with_size cogl_atlas_texture_new_from_file cogl_atlas_texture_new_from_data cogl_atlas_texture_new_from_bitmap The plan is to remove auto-texture apis like cogl_texture_new_from_file since they are a bit too magic, but that means we need an explicit way for users to allocate texture that will go in the atlas. Although the _new_from_file() api is arguably redundant since you can use _bitmap_new_from_file() followed by _atlas_texture_new_from_bitmap() we don't want to loose any of the convenience that cogl_texture_new_from_file() had.

texture: split out high-level texture constructors This splits out the very high level texture constructors that may internally construct one of several types of lower level texture due to various constraints.

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. This ability to convert bitmaps in-place has been integrated across the different components as appropriate. In updating cogl-texture-2d-sliced.c this was able to remove a number of other GL specific parts to how spans are setup.
