LibGfx: Simplify draw_anti_aliased_line() by avoiding transform callback
...
Instead of taking a callback that performs the coordinate transformation
we now just take a bool template parameter.
Thanks to Idan for suggesting this! :^)

We're already doing this for Gfx::Painter, so let's do it here as well.

LibGfx: Add fast path to AA line drawing with simple 2D transform
...
If the effective 2D transform is just a basic translation, we now simply
translate the underlying painter before & after drawing AA lines.
This avoids all the extra math that otherwise has to happen when mapping
points through an affine transform.
This noticeably increase "mousing around" performance on Wikipedia. :^)

Previously the painter would crash if scaling was enabled.

This improves the appearance of anti-aliased lines significantly.

Follows the efficient algorithm from this paper:

Can be extended ellipses in future.

This is still quite bad, but it's much more pleasing to look at when
drawing random SVGs :^)

LibGfx: Start a very basic anti-aliased Painter implementation
...
This can currently draw AA lines (and by proxy, AA paths), and passes
all its output through a 2D affine transform to an underlying
Gfx::Painter.
