The only way the user has to set the mipmap filters is through the material/layer API. This API defaults to GL_LINEAR/GL_LINEAR for the max and min filters. With the main use case of cogl being 2D interfaces, it makes sense do default to GL_LINEAR for the min filter. When creating new textures, we did not set any filter on them, using OpenGL defaults': GL_NEAREST_MIPMAP_LINEAR for the min filter and GL_LINEAR for the max filter. This will make the driver allocate memory for the mipmap tree, memory that will not be used in the nominal case (as the material API defaults to GL_LINEAR). This patch tries to ensure that the min filter is set to GL_LINEAR before any glTexImage*() call is done on the texture by setting the filter when generating new OpenGL handles. |
