[mcclim-devel] another incremental redisplay problem

[Robert Strandh]

Hello,

Incremental redisplay uses objects of type output-record to determine
what to redisplay.  Output records are subclasses of
bounding-rectangle.  But bounding-rectangle is not a subclass of
region, so one cannot use region-intersects-region-p to check whether
two output records overlap.  But this is in fact the case in the
current incremental redisplay code.
