Making conversion hints available to ImageHandler implementations, too.

(Re-)implemented Graphics2D support for PCL. It can be disabled by fox:conversion-mode="bitmap" if necessary.
Fixed a bug with non-uniform image scaling when encoding bitmap images.
Commented some code that did not reliably convert color images to grayscale. The (probably slower) fallback code is used instead.
Some performance improvements for text painting using bitmaps when <rendering>speed<rendering> is selected.
Removed the RenderingContext interface from RendererContext since it's not used.
