Subject: [PATCH] Use correct colormap with -t

Using the default colormap on a drawable w/ specific (ARGB) colormap for
rendering the arcs will lead to random colors being picked (typically
"white", but it can actually be anything) for the arcs. You have to use
the colormap specific to the drawawble (window)

Fixes #26
