Fix issue after commit 50282: float texture painting non-color data textures did

not do correct partial updates, now it remembers if the opengl texture is a
non-color data texture or not and takes that into account for the update.

Also includes some renaming ncd => is_data for consistency with color space
terminology used elsewhere.
