What is so wrong in this case to have the cursor follow the only possible path 
that is within the constraints. Because if you don't then you end up with a 
pointer position that doesn't correspond to the current selection anymore.

In this case we have a corner of an aspect constrained rectangle selected. 
Both x and y movements are allowed but as these two have to a strict 
relationship any movement by the user that doesn't follow this relationship 
(for every 3 pixels horizontally move 2 pixels vertically) will end up having 
the pointer and the corner being so far apart that the visual relationship 
between the pointer and the selection isn't aparent any more. I have found a 
partial solution to this problem yesterday evening (still some quirks to work 
out) but the problem basically is only reduced by the code that tries to keep 
the selection as close as possible to the pointer, there still are times when 
they end up virtually in different corners of the screen...
