Flat and Square caps are implemented.
Bevel joins are implemented.
Round caps, Round joins and Miter joins are left for another PR.

PaintOp.Rect is the wrong abstraction; it implies a clip operation
better handled by package clip, and not all paints need it (colors).
Furthermore, it's awkward to specify a PaintOp that fills up the
current clip area, regardless of its size.
Redefine PathOp to mean "fill current clip area".
API change. Replace uses of PaintOp.Rect with a TransformOp applied
before the PaintOp.
Leave a TODO for the PathOp infinity area.
Fixes gio#167

We're about to remove PaintOp.Rect. Replacing PaintOps with Fill or
FillShape where possible will ease the transition.
Using Fill in tests exposed a problem with the infinity in paint.Fill.
Adjust it for now; it will be removed later.

Uses app/headless to create a set of test cases for drawing operations, including clipping
textures and transforms. This commit tests for approximate pixel matches, if future changes affect
local drawing operations it will be easy to change the reference images, it thus becomes and
should be an intentional operation if changes lead to local changes in drawn results.
Ideally we should be able to make the tests check for exact pixel matches down the line to ensure
consistent results between platforms.
