With 24d08e0bae, the ability to view UVs
in the Image Editor was introduced in all modes, not just Texture Paint
and Edit Mode. This introduced a new flag that was enabled by default,
causing UVs to be displayed in any of the Image Editor modes.
While this is helpful for some workflows, it is unnecessarily
distracting for many usecases when using the Image and Mask modes of the
Image Editor. To remedy this, this PR adds various polls to ensure
that these are only shown in the Paint Mode of the Image Editor and the
UV Editor. Further thought should be put into the potential separation
between the different usecases of this editor, but that is out of scope
for now.
