fix paths and remove dead code

More Skia driver cleanup.

Fix the GN build for Skia.
Remove unused functions from header.
Remove agg setup that is not required.

Change path construction to use the SkCanvas matrix to position the path
rather than converting the points directly.

Draw stroked paths using Skia rather than generated the filled path.
Pin the minimum stroke width to 1 px in device space to mimic PDF's stroke
dropout control.

Factor out flipped and non-flipped matrices.

Add some debugging code.

Set the bitmap filter quality to high. This helps a lot with 1 bit sources.
