Benjamin Otte b5345b7f25 glrenderer: Handle filters differently
Instead of uploading a texture once per filter, ensure textures are
uploaded as little as possible and use samplers instead to switch
different filters.

Sometimes we have to reupload a texture unfortunately, when it is an
external one and we want to create mipmaps.
