lyx_mirror/src/FontInfo.cpp
Vincent van Ravesteijn a58e160745 branch: Fix bug 5629: Hard to distinguish between added and deleted text. 
http://bugzilla.lyx.org/show_bug.cgi?id=5629. 

Backport of:
- (r28420) Add a new Color class. This class makes it possible to specify a color as a merging of two other colors.
- (r28421) Use the new Color class in the Painter code. 
- (r28422) Add a new member to FontInfo? denoting the color to be used when painting. 
- (r28423) Add a new customizable color that indicates the merge color for deletion.
