… follow theme colors or not.
This is an update to MR !1370, as a result of testing and usability
meetings with Aryeom. While we understand that some people may want the
brush dockable to not display as some huge white "stain" in the middle
of an otherwise dark GUI (or other colors, depending on the chosen theme
and color scheme), brushes are not part of the GUI. When you look at
brush previews, you don't expect these to follow theme. And for sure,
painters more often paint over a white canvas than a gray or dark canvas
(or other colors), even though this is not an "always true" either. But
it's probably a better bet than following theme (which is closer to
"always false"!).
Therefore, what this additional commit does:
* By default, the brush previews still show as black on white;
* Nevertheless there is now a button (using the Preferences' theme icon)
in the Brushes dockable which allow to switch to theme colors
following brush previews.
* This setting is a GimpGuiConfig property, which means it will stick
across sessions.
