This patch adjusts the default Breeze color scheme to produce the final Tools Area
appearance proposed in T10201. The following changes are made:
- The titlebar background color is darkened a bit
- The window background color is lightened a bit to increase contrast with the Tools Area
- The view background is lightened a bit to preserve contrast with the window BG color
- Other colors that were using the window and view BG colors are updated to the new values
- For consistency, the Breeze Light color scheme receives all of the above changes except for the titlebar coloration change
- The titlebar gradient is turned off by default
- The close button background circle is made red by default
Depends on D27669
