There is not integrated into the Paint program, and Mac OS X, but there are a myriad you can get in different price ranges (including free programs, of course).
LiveQuartz, I must admit have not tested, seems to do good work, you could try. http://www.livequartz.com/
ChocoFlop is nondestructive and with the exception of ugly buttons, it can be pretty cool. http://www.chocoflop.com/
Pixelmator is not free, but it is probably the best you get for your $ 59. http://www.pixelmator.com
