Sometimes you want to move the Rect by its right or bottom edge without
resizing the rect in the process. There are probably better names for
this but nothing comes to mind at the moment.
This was a workaround to be able to build on case-insensitive file
systems where it might get confused about <string.h> vs <String.h>.
Let's just not support building that way, so String.h can have an
objectively nicer name. :^)
These are useful when doing widgets that can be switched between vertical
and horizontal mode, such as GSlider. The idea is that instead of using
"x" and "y" directly, you use the "primary" and "secondary" offset/size
for the Orientation you're configured in.
Instead of LibGUI and WindowServer building their own copies of the drawing
and graphics code, let's it in a separate LibDraw library.
This avoids building the code twice, and will encourage better separation
of concerns. :^)
