pixel mask not applied during eta-omega map creation

[ksg52]

HEXRDGUI version: 1.1.4.dev135+g1946cd0b
HEXRD version: 0.9.9.dev120+geae142b

When I apply a mask in HEXRDGUI to mask out invalid pixels, the mask appears to be active when viewing the image series, but is not being applied when creating eta-omega maps. example screenshots below:

In the image series view, masked pixels are highlighted in green. In the eta-omega map, bands of very high values at fixed eta ranges are the nominally-masked pixels.

Turning on filtering in the eta-omega map eliminates these bands and allows me to proceed with find-orientations and fit-grains, but it does seem like the mask in the instrument file should be applied prior to eta-omega map creation so that the masked pixels are never included in calculations.

Yeah this will be an easy fix thankfully

@donald-e-boyce I'm thinking about adding a new operation to the ProcessedImageSeries, maybe named mask, that will mask out specified pixels before returning the image. We would be able to use that here. What do you think?

This would get the eta omega map generation code in hexrd to automatically ignore those invalid pixels.

That sounds like a good idea. It would definitely work. Since the mask is in the instrument file, I think it's reasonable to do that. If you wanted to turn the mask on / off and try different things, that would be a different use.
