Subject: The check for Color_math would fail if the font color is changed
X-Git-Tag: 2.0.0~3338
X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;h=dbb5ac93ea8d2310038322a81e25242f32e35f71;p=features.git

The check for Color_math would fail if the font color is changed
in mathed, so implement a strategy which is immune to color changes.
