procedure FastGaussianBlur(img: TImage32; const rec: TRect; stdDev: integer; repeats: integer);

This procedure produces a very good approximation of GaussianBlur, but it's very much faster. The number of repeats will determine blur quality, where more repetitions will produces better quality blurs. Logically, more repetitions will also be at the expense of speed. Usually the best compromise between speed and quality is with 1 or 2 repetitions. Default = 2 repeats.
