-// wxWindows previously always considered that toolbar buttons have light grey
-// (0xc0c0c0) background and so ignored any bitmap masks - however, this
-// doesn't work with XPMs which then appear to have black background. To make
-// this work, we must respect the bitmap masks - which we do now. This should
-// be ok in any case, but to restore 100% compatible with the old version
-// behaviour, you can set this to 0.
