Re: [gef-dev] Ghost shape, Mac OS X xor issue, and a possible solution

[Randy Hudson <hudsonr@xxxxxxxxxx>]

Besides requiring GDI+ library on windows
2000, and Cairo on Linux, painting using alpha is probably 1-2 orders of
magnitude slower than XOR.  Any change we make should probably be
OS-specific.

I think that is some cases the outline
partially overlaps the fill. Using alpha for both would reveal that.

Oh. Does that mean that setAlpha isn't supported on all platforms?  
Then it should be deprecated,too ;)
setAlpha(int) is a method of org.eclipse.swt.graphics.GC. It's a non- 
deprecated, public method of the SWT package.  
org.eclipse.swt.graphics.GC.setXORMode(boolean) _is_ deprecated!
