Add convex hull algorithm from cairo sources. Used to constrain pens to

    convex shapes so that the convolution algorithm works correctly.
Reduce default tolerance to 1/16 of a pixel
Use convex hull of pen.
Snap horizontal and vertical elements of glyphs to pixel boundaries. Snap
    stem widths to integer amounts. Add slanting and emboldening
Add space and box
Avoid using __inline as it increases size dramatically
Use <= tolerance_squared as that may be zero
Swizzle code to show off recent changes
