LibGfx+PixelPaint: Add Point::end_point_for_aspect_ratio method

Browse source 
Previously we only had `Point::end_point_for_square_aspect_ratio`,
which was convenient for PixelPaint but assumed the aspect ratio
was always fixed at 1. This patch replaces it with a new mthod that
takes in an arbitrary aspect ratio and computes the end point based
off that.

There's some explicit casting going on in `Point.cpp` to ensure that
the types line up, since we're templating Point based on `T`.`
