Misc. updates.

Use the freedesktop.org logo with part of it translucent as the destination
image.  Load the dst image every time we start the test loop.  Use a test image
with a more interesting alpha channel (the X.Org logo with a white X).

Add an option to create a 32-bit ARGB window instead of one with the default
visual.  In that mode, create the destination pictures with a format that has
alpha so ops like PictOpIn will work correctly.

Reduce the test time from 5 seconds to 2 seconds to make things go a little
faster.

Change the mask image to have colors so component alpha will look interesting.
