In order to do linear-correct filtering cheaply when scale filtering is disabled, we need to know whether or not texture coordinates will always sample from texel centers. This can be computed at the scene item level relatively easily, and passed along to sources when rendering. Scene items will use obs_source_set_texcoords_centered to set hint status, and sources will use obs_source_get_texcoords_centered to retrieve it.
