Add EmbedderTest for adding and filling paths

The PathObject uses GraphState to obtain the bounding box, so I set defaults,
according to Table 4.2 of PDF spec 1.7. Not testing stroke for now because the
default line width seems to be too small and is not being rendered.

Methodology: add the test methods to the RenderPage method in pdfium_test, and
run with --png and --md5. Check that the png is reasonable with respect to the
expected result, and use the output md5 on the embeddertest.
