Previously, calling `.right()` on a `Gfx::Rect` would return the last
column's coordinate still inside the rectangle, or `left + width - 1`.
This is called 'endpoint inclusive' and does not make a lot of sense for
`Gfx::Rect<float>` where a rectangle of width 5 at position (0, 0) would
return 4 as its right side. This same problem exists for `.bottom()`.
This changes `Gfx::Rect` to be endpoint exclusive, which gives us the
nice property that `width = right - left` and `height = bottom - top`.
It enables us to treat `Gfx::Rect<int>` and `Gfx::Rect<float>` exactly
the same.
All users of `Gfx::Rect` have been updated accordingly.
This is done to be consistent with enclosing_int_rect() which is
used elsewhere to work out offsets in PaintStyles. Without this, you
can get an off-by-one in painting.
This makes all the code for fill_path() member functions of the painter,
and moves them into a new FillPathImplementation.cpp. This allows us
to avoid polluting Painter.h with implementation details, and makes
the edit, compile, retry loop much shorter.
