Create a subset of skia support for paths only

Create a subset of skia support for paths only

This removes the need for agg, without providing
full Skia support.

It doesn't work yet, but it does compile and run
for simple PDFs.

Cool, so the USE_PATHs variant is using enough of Skia that we can remove AGG?
Is the performance similar between the two?

This seems like a really good half way point to getting us to Skia. We can
remove AGG and start incrementally making our Skia backend better without the
baggage of maintaining the old code paths.

Let's consolidate all of these header if's into fewer blocks if possible.
