Hi all,
I have a weird problem which may be a bug, but hopefully has a solution. I am
drawing a histogram whose bins are coloured according to an arbitrary colour
map. This involves drawing a series of filled rectangles whose height is
proportionally to the frequency of the bin, and then
This is probably due to the fact that we use different rendering
pipelines in some cases when the colors are translucent (for example, we
may use X11 requests to render on Linux and Solaris when the colors are
solid, and then we may use readback, modify pixels, writeback
mechanisms to deal
