Add more draw functions, make less code use rectangles

Browse Source 
Some code still used rectangles to draw things like lines and pixels,
so this commit adds more draw functions to support drawing lines and
pixels without directly using the renderer.

Aside from making generated minimaps draw points instead of 1x1
rectangles, this commit also batches the point drawing for an
additional speed increase.
