LibGfx: Add a draw_scaled_bitmap() variant that takes a FloatRect as src_rect
Consider
draw_scaled_bitmap({0, 0, 10, 10}, source, {0, 0, 5, 5}).
Imagine wanting to split that up into two calls, like e.g. the
compositor when redrawing the background with damage rects. You really
want to be able to say
draw_scaled_bitmap({0, 0, 5, 10}, source, {0, 0, 2.5, 5})
but up to now you couldn't. Now you can.
This makes painting very low-res images (such as tile.png) in mode
"stretch" work much better.
