This makes it a bit easier to avoid calling parser->set_document, an

LibPDF: Fix "incorrect" matrix multiplication in Renderer
...
Incorrect is in quotes because the spec (both 1.7 and 2.0) specify this
multiplication as it was originally! However, flipping the order of
operations here makes the text in all of my test cases render in the
correct position.
The CTM is a transformation matrix between the text coordinate system
and the device coordinate system. However, being on the right-side of
the multiplication means that the CTM scale parameters don't have any
influence on the translation component of the left-side matrix. This
oddity is what originally led to me just trying this change to see if
it worked.

This decreases the memory consumption by LibPDF by 4 bytes per Value,
compensating exactly for the increase in an earlier commit. :^)

LibPDF: Add support for the CalRGB ColorSpace
...
This isn't tested all that well, as the PDF I am testing with only uses
it for black (which is trivial). It can be tested further when LibPDF
is able to process more complex PDFs that actually use this color space
non-trivially.

This completely ignores the actual path and just uses its bounding box,
