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.

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.

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.
