Damien Lespiau 87bc616d34 framebuffer: Support texture based depth buffers ... This commit introduces some new framebuffer api to be able to enable texture based depth buffers for a framebuffer (currently only supported for offscreen framebuffers) and once allocated to be able to retrieve the depth buffer as a texture for further usage, say, to implement shadow mapping. The API works as follow: * Before the framebuffer is allocated, you can request that a depth texture is created with cogl_framebuffer_set_depth_texture_enabled() * cogl_framebuffer_get_depth_texture() can then be used to grab a CoglTexture once the framebuffer has been allocated.		2013-01-18 10:53:29 +00:00
