ABOUT REV 0121 - 6 November 2006

Adds printing, fixes a last-minute createGraphics() regression in 0120,
and some other minor tweaks.

[ features! ]

+ Printing a tab is now supported (but with caveats)
 http://dev.processing.org/bugs/show_bug.cgi?id=27
 The"Page Setup" dialog doesn't work very well because Java seems
 to suck at printing, and sucks differently on different platforms:

 Also, only the current tab is printed:

+ Added background() with alpha parameters, but only for use with
 graphics created by createGraphics(). Also, it replaces the pixels
 with pixels that have that alpha, it's not like drawing a semi-
 transparent rect() onto the screen. For instance, to make a drawing
 surface transparent again, use background(0, 0, 0, 0). Using
 background(0, 0, 0, 128) will replace the background with black
 pixels that are 50% transparent, it will not fade the existing
 image toward black, use a rect() for that.

[ bug fixes ]

+ size(), beginRecords(), beginRaw(), and createGraphics() were broken
 for file-based renderers in 0120
 http://dev.processing.org/bugs/show_bug.cgi?id=434

+ Fixed overly fat buttons on OS X due to a previous workaround that's
 no longer a problem because we're using (testing?) the Quaqua L&F.

+ Fixed a bug with 'hidden' code causing an error inside rebuildMenu()
