It's okay. I screw up about 50 times a day usually. :)

I was in the process of converting my code to the new syntax and tried 
this instead so scaling would work:

Old:

belevation.PaintImage(dshading, 0, 0, tgsize * 128, tgsize * 128, 
Fix(cx) - tgoffset, Fix(cy) - tgoffset, tgsize, tgsize)

New:

belevation.PaintImage(dshading.Resize(tgsize * 128, tgsize * 128), 0, 0, 
Fix(cx) - tgoffset, Fix(cy) - tgoffset, tgsize, tgsize)

While that doesn't throw an error, I can't tell if it's working because 
despite converting my code to remove the destination size parameters the 
graphics are totally f'cked up (attached). Crazy, no?

Even with the mistake, should this be working or am I doing something 
wrong? And one final question, what was the revision number before that 
change? I have some new, unrelated code that I need to test.
