Sun Apr 21 12:41:14 2002 UTC (12 years ago) by brian
Branch: MAIN
Changes since 1.12: +29 -27 lines
Sundry fixes to run without multiprocessing support.

Added images/ to hold bitmaps for tests.

Added looks/ to hold neutral look-and-feel realizer packages.

Added Examples/gadget-test to test many gadgets with a look and feel.

Added a pixie look and feel, and a pixie/clx to work with the clx backend.

Added drawing support in the CLX backend for ovals and circles.

Fixed pixmaps to work with with-output-to-pixmap with draw-image, etc.

Moved sheet-leaf-mixin to standard-gadget-pane so it doesn't break radio-box-pane, etc.

Misc fixes.
