The updateBackgroundColor mechanism seems to be very seriously 
flawed and needs to be rewritten, as it is one of the main bottlenecks 
in the code.
The problem is this: the various calls to updateBackgroundColor() 
propagate down to the run level, where 
fp_Run::updateBackgroundColor() querries the PieceTable (!!!) for 
the background colour property. This is not the way it should be -- 
*the only* place the runs should ever querry the PT for properties is 
::lookupProperties() which in turn is only to be called in response to 
formatting changes in the PT.
If the background colour needs to change because the PT has 
changed, then let it be done in ::_lookupProperties; if the PT has not 
changed, then the updateBackground colour has no business of 
querring the PT. So my question is why do we need 
updateBackground() colour at all?
