Add a test for getting the component sizes from different fbs This adds a test which creates two offscreen framebuffers, one with just an alpha component texture and the other will a full RGBA texture. The bit sizes of both framebuffers are then checked to verify that they either have or haven't got bits for the RGB components. The test currently fails because the framebuffer functions don't bind the framebuffer before querying so they just query whichever framebuffer happened to be used last.

cogl: Add missing function declarations In plenty of places a non-static function was defined but didn't have the corresponding declaration. Fix this by adding them, or alternatively making them static.

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. Reviewed-by: Neil Roberts <neil@linux.intel.com> (cherry picked from commit 99a53c82e9ab0a1e5ee35941bf83dc334b1fbe87) Note: there are numerous API changes for functions currently marked as 'unstable' which we don't think are in use by anyone depending on a stable 1.x api. Compared to the original patch though this avoids changing the cogl_texture_rectangle_new_with_size() api which we know is used by Mutter.

CoglOffscreen *offscreen_a =
Declare interface types as void and remove cast macros This declares the interface types CoglFramebuffer, CoglBuffer, CoglTexture, CoglMetaTexture and CoglPrimitiveTexture as void when including the public cogl.h header so that users don't have to use lots of C type casts between instance types and interface types. This also removes all of the COGL_XYZ() type cast macros since they do nothing more than compile time type casting but it's less readable if you haven't seen that coding pattern before. Unlike with gobject based apis that use per-type macros for casting and performing runtime type checking we instead prefer to do our runtime type checking internally within the front-end public apis when objects are passed into Cogl. This greatly reduces the verbosity for users of the api and may help reduce the chance of excessive runtime type checking that can sometimes be a problem. (cherry picked from commit 248a76f5eac7e5ae4fb45208577f9a55360812a7) Since we can't break the 1.x api this version of the patch actually defines compatible NOP macros within deprecated/cogl-type-casts.h
