And though it works, it gives various errors. On the -lockFocus method it
prints out:
*** Assertion failure in -[NSThemeFrame lockFocus],
/SourceCache/AppKit/AppKit-1038.25/AppKit.subproj/NSView.m:5237
2010-05-15 14:43:07.750 CocoaJunk[2204:a0f] -[NSThemeFrame(0x100418f20)
lockFocus] failed with window=0x1001215a0, windowNumber=-1, [self
isHiddenOrHasHiddenAncestor]=0
If you comment out the -lockFocus and -unlockFocus lines it still works but
prints out:
<Error>: CGContextSetFillColorWithColor: invalid context 0x0
and more.
Hmm...
