12.5.2 Transparency on X11/Motif

Some image formats with transparency are now supported on X11.

When using gp:draw-image on X11, graphical images loaded from files (for example some GIFs and some TIFFs) are now drawn using the transparency mask from the image.

In LispWorks 5.0 and previous versions, this only worked on Cocoa and Microsoft Windows.
