DrawFill made not stupid

made it more consistent with other drawing functions; doesn't draw off of the sides, and doesn't ignore snapping or widths for reasons that don't make sense (for instance: the green bar in MI's test script showed above the blue one in non-green resolutions in 2.1.17)

Clearly much better than what I was doing in my own branch, makes sense
