I've been sold on the unsigned vs signed type issue for and
only for the x and y coordinates.
The first version of ae.utils.graphics had unsigned
coordinates. As I found out, this was a mistake.
A rule of thumb I discovered is that any numbers you may want
to subtract, you should use signed types. Otherwise,
operations such as drawing an arc with its center point
off-canvas (with negative coordinates) becomes unreasonably
complicated.
giving that `int` and `uint` are freely interchangeable...
`uint` is better, as it allows only one bound check in `if`,
and without casts. ;-)
That's a poor reason. Optimizing x>=0 && x<100 to an unsigned
check is such a basic optimization, even DMD can do it.
