The CoglTexture2DSliced backend has a fallback for when the framebuffer extension is missing so it's not possible to use glGenerateMipmap. This involves keeping a copy of the upper-left pixel of the tex image so that we can temporarily enable GL_GENERATE_MIPMAP on the texture object and do a sub texture update by reuploading the contents of the first pixel. This patch copies that mechanism to the 2D and 3D backends. The CoglTexturePixel structure which was previously internal to the sliced backend has been moved to cogl-texture-private.h so that it can be shared. |
