(35S) Photo resolution from MPixels and aspect ratio

[mchris]

For those of us who engaged in photography, we sometimes want to find the horizontal and vertical resolution of a sensor from the Megapixels (P) and aspect ratio (R). The following program uses only the stack (Y=Megapixels, X=Ratio) and the answer returned to X=Horizontal res. and Y=Vertical res.
The program is based on the formulas:HRes=SQRT(P*R), YRES=SQRT(P/R).
