Instead, do getBounds().getExpanded(-1,-1).

Thank's it is working with cairo 1. It is possible to check if if
antialias (cairo) is available. In that way it would be possible to
activate antialias only if cairo has been installed.

boolean advancedGraphicsInstalled = gc.getAdvanced();
gc.setAdvanced(false);
These methods aren't reflected in the Graphics class yet, though.

Hi Pratik,
how can I access the GC? The Graphic Context is hidden by SWTGraphics and
not accessible from outside.

Until then, as a workaround, you can create your own GC.
