Damien Lespiau	23717452bf	cogl-buffer: Use TEXTURE as the only value for CoglBufferUsageHint ... We should try to use more explicit defines than GL for our hints. For now we only support using a CoglBuffer to generate textures.	2010-02-08 17:14:49 +00:00
Damien Lespiau	273fd23742	cogl-buffer: make sure the code compiles on GL ES ... OpenGL ES has no PBO extension, so we fallback to using a malloc'ed buffer. Make sure the OpenGL-only defines don't leak into the OpenGL ES compilation.	2010-02-08 17:14:49 +00:00
Damien Lespiau	40b73a8c0c	cogl-buffer: add an abstract class around openGL's buffer objects ... Buffer objects are cool! This abstracts the buffer API first introduced by GL_ARB_vertex_buffer_object and then extended to other objects. The coglBuffer abstract class is intended to be the base class of all the buffer objects, letting the user map() buffers. If the underlying implementation does not support buffer objects (or only support VBO but not FBO for instance), fallback paths should be provided.	2010-02-08 17:14:49 +00:00
