Neil Roberts	1df0e36c6c	cogl: Use a vtable for the texture backends instead of a type and switch ... Instead of storing an enum with the backend type for each texture and then using a switch statement to decide which function to call, we should store pointers to all of the functions in a struct and have each texture point to that struct. This is potentially slightly faster when there are more backends and it makes implementing new backends easier because it's more obvious which functions have to be implemented.	2009-11-25 13:47:28 +00:00
Robert Bragg	5387aa0e9e	[cogl-spans] split out cogl-spans code from cogl-texture-2d-sliced ... When we implement atlas textures we will probably want to use the spans API to handle texture repeating so it doesn't make sense to leave the code in cogl-texture-2d-sliced.c. Since it's a standalone set of data structures and algorithms it also seems reasonable to split out from cogl-texture.	2009-10-16 18:58:52 +01:00
Vladimir Nadvornik	65015a137e	[cogl-texture] Split CoglTexture into an abstract class + CoglTexture2dSliced ... cogl-texture-2d-sliced provides an implementation of CoglTexture and this seperation lays the foundation for potentially supporting atlas textures, pixmap textures (as in GLX_EXT_texture_from_pixmap) and fast-path GL_TEXTURE_{1D,2D,3D,RECTANGLE} textures in a maintainable fashion.	2009-10-16 18:58:51 +01:00
