commit ee7cc9e7889498c7ed3574b85e7294fff1bb45b1
Author: Robert Bragg <robert linux intel com>
Date: Tue May 17 00:05:54 2011 +0100
Make CoglTexture2D public as experimental API
This exposes a CoglTexture2D typedef and adds the following experimental
API:
cogl_is_texture_2d
cogl_texture_2d_new_with_size
cogl_texture_2d_new_from_data
cogl_texture_2d_new_from_foreign
Since this is experimental API you need to define
COGL_ENABLE_EXPERIMENTAL_API before including cogl.h.
Note: With these new entrypoints we now expect a CoglContext pointer to
be passed in, instead of assuming there is a default context. The aim is
that for Cogl 2.0 we won't have a default context so this is a step in
that direction.
