Dear folks,
can anyone reproduce this? (Live ConTeXt on the garden seems to run
into this \faststartcolor thing ... with pdfTeX.)
Uncomment the page background overlay and the top bit of the frames'
titles will be chipped off ... doesn't happen for the plain vanilla
color background on my machine.

the boundingbox sets the final size of the gfx. if your gfx is larger
than the bb, things will overlap. just enlarge the bb, so that it fits
the gfx.
