====== RGB map brush ======
The 'RGB map brush' window is activated by selecting the '//Tools->RGB brush//' option in the menu or by viewing a RGB map layer (e.g. light map, texture or other custom 24-bit map), and then clicking on the 'edit active map layer' toolbar icon shown below:

Left-clicking and dragging the mouse around on the RGB map will apply the setting from this window.
If you change the mouse mode (e.g. to zoom, etc.), you can re-activate this tool by left-clicking within the window.
