Would be nice if you coult wrap the use of malloc and XpmFreeXpmImage
in a RAII object.

The principle behind scaling is simple: It's raytracing.
So, for each destination pixel, calculate which pixel it corresponds
to in the source picture.

Ok, the idea is easy enough. The devil, as they say, is in the detail.

Two reasons not to:
1. simple cropping, rotation, scaling is easy and simple is enough for
GImageXPM which is just a proof of concept image loader. The real image
