ppmrotate does not work the way I want it to -- it enlarges the output
bitmaps for rotations which are not multiples of 90 degrees.

I want to rotate a bitmap and have it retain its original size. I.e.,
rotate 10 degrees, say, about the center point of a 32x32 bitmap, and have
the output bitmap be 32x32 with the same center point, which entails doing
some cropping of the part that's rotated beyond the 32x32 frame.

I realize I could write a program to do this myself, but I'd rather use
an existing tool....
