Improved collections
--------------------

The individual items of a collection may now have different alpha
values and be rendered correctly.  This also fixes a bug where
collections were always filled in the PDF backend.

------------------------------------------------------

When putting multiple images onto the same axes, the background color
of the axes will now show through correctly.
