Robert Bragg 869a2b4167 [cogl-offscreen] Cleans up the cogl offscreen API and adds documentation ... There were several functions I believe no one is currently using that were only implemented in the GL backend (cogl_offscreen_blit_region and cogl_offscreen_blit) that have simply been removed so we have a chance to think about design later with a real use case. There was one nonsense function (cogl_offscreen_new_multisample) that sounded exciting but in all cases it just returned COGL_INVALID_HANDLE (though at least for GL it checked for multisampling support first!?) it has also been removed. The MASK draw buffer type has been removed. If we want to expose color masking later then I think it at least would be nicer to have the mask be a property that can be set on any draw buffer. The cogl_draw_buffer and cogl_{push,pop}_draw_buffer function prototypes have been moved up into cogl.h since they are for managing global Cogl state and not for modifying or creating the actual offscreen buffers. This also documents the API so for example desiphering the semantics of cogl_offscreen_new_to_texture() should be a bit easier now.		2009-05-02 04:12:26 +01:00
