This gives much flexibility in contrast to previous fixed
pixmaps. E.g. lane symbols could overlap now, which was
not possible before.
However, this patch does not change any drawing aside
from fixing the ugly spaces in the lanes on commits with
tag/branch labels, and shows the selection even in the
graph background (not really sure if this is wanted;
however, easy to change).
This patch does not cleanup the old pixmap drawing; it even
uses the width of one pixmap as global lane width.
The new painting code regroups the drawing commands in
multiple switch-statements to prepare for far simpler code
with booleans for different elements, and not one type only.

Hi Marco,
the change looks bigger than it really is because of the
pure rearrangement of the drawing code.
I hope I used your indentation style.
