in an attempt to get a somewhat feature-complete beta out on the street,
the standard 2D renderer (now called PGraphics, formerly BGraphics) was
disabled, although its 3D functionality made its way into PGraphics3.

need to finish this renderer and get it working again so we can drop the
slow ass Java 2D renderer as the default.

tasks include things like a proper engine for tessellation, dealing with
all manner of stroke caps and joins, as well as smoothing and alpha.

gave up on 1.1 support as of release 0126 and later. moving ahead with 1.4+.
