Since you don't really need any color info when exporting UV layouts,
changed the FBO to using grayscale to save system resource especially
for exporting large images.

Note: this needs blender/blender#110630 to be merged first.

This looks like it will produce an image with no alpha. A typical use-case for this addon will be to use the resulting file and overlay it on top of whatever you're painting as a layer rather than painting directly on the resulting file.

Note that exporting UV layouts uses material color, so I don't think the premise of this PR is correct.

@jesterking You could still use multiply/overlay mixing for these kind of single channel images to achieve the same effect.

@ideasman42 Hummm looks like only filling uses vertex color... Maybe I'll go add an option there for people that want to have mono output.

and yes I use it as multiply, or even we can use it as a mask or even, we can use it just as a resource for selection tool
