I have made changes to the UT_RGBcolor class, so that it can represent a transparent colour -- I have taken the approach suggested by Joaquin with an extra bool, because it makes it possible to create a transparent colour that otherwise appears to be white and that way we do not need to modify the graphics classes to draw white bacground when the colour is set to transparent.
I also removed the propety querry from fp_Run::updateBackgroundColor(); this fix does not deal with the fact that the function itself is probably called more often than it should be, but I will that to Joaquin. files: ut_misc.cpp/h, fp_Run.cpp/h, fp_TextRun.cpp Tomas
