This exposes CoglTextureRectangle in the experimental cogl 2.0 api. For now we just expose a single constructor; cogl_texture_rectangle_new_with_size() but we can add more later. This is part of going work to improve our texture apis with more emphasis on providing low-level access to the varying semantics of different texture types understood by the gpu instead of only trying to present a lowest common denominator api. CoglTextureRectangle is notably useful for never being restricted to power of two sizes and for being sampled with non-normalized texture coordinates which can be convenient for use a lookup tables in glsl due to not needing separate uniforms for mapping normalized coordinates to texels. Unlike CoglTexture2D though rectangle textures can't have a mipmap and they only support the _CLAMP_TO_EDGE wrap mode. Applications wanting to use CoglTextureRectangle should first check cogl_has_feature (COGL_FEATURE_ID_TEXTURE_RECTANGLE). Reviewed-by: Neil Roberts <neil@linux.intel.com> |
