The vertical coordinates for truetype fonts are different somehow.
We compensated a bit for that; now we compensate some more.
This is still not 100% perfect, but much better than before.
Since we can't clip against a general path yet, this clips images
against the bounding box of the current clip path as well.
Clips for images are often rectangular, so this works out well.
(We wastefully still decode and color-convert the entire image.
In a follow-up, we could consider only converting the unclipped
part.)
Turns out the width/height in a `re` command can be negative. This
results in rectangles with different winding orders. For example, a
negative width results in a reversed winding order.
Previously, this was lost by passing the rect through an
`AffineTransform` before constructing the path. So instead, this
constructs the rect path, and then transforms the resulting path.
Now, instead of resolving "transform" and "transform-origin" during the
construction of the stacking context tree, we do so during the layout
commit.
This is part of a refactoring effort to make the paintable tree
independent from the layout tree.
The predictor code assumed that all stream data is image data
(...which would make sense: trailing data there is wasted space).
But some PDFs have trailing data there, e.g. 0000257.pdf, so be
forgiving about it.
Now, we will evenly distribute the remaining free space across tracks
using the auto max-tracks sizing function, exactly as the specification
states. Many tests are affected, but they are not visually broken.

Relative paths cause issues in a couple of ways:
- `open_project()` sets the working directory to that path, and then
opens a project at that same path. This means opening `./foo` goes to
`./foo`, and then tries to open `./foo/foo`.
- Even with that rearranged, we would then have issues with trying to
open files, because again we would try to open `./foo/foo/file`
instead of `./foo/file`.
- The relative path would get saved in "Recent Projects" which is wrong.
Absolutizing the path before using it means we avoid these issues, and
without having to rearchitect everything. :^)
There's now two namespaces, RIFF (little-endian) and IFF (big-endian)
which (for the most part) contain the same kinds of structures for
handling similar data in both formats. (They also share almost all of
their implementation) The main types are ChunkHeader and (Owned)Chunk.
While Chunk has no ownership over the data it accesses (and can only be
constructed from a byte view), OwnedChunk has ownership over this data
and is aimed at reading from streams.
OwnedList, implementing the standard RIFF LIST type, is currently only
implemented for RIFF due to its only user being WAV, but it may be
generalized in the future for use by IFF.

This splits the RIFFTypes header/TU into the WAV specific parts, which
move to WavTypes.h, as well as the general RIFF parts which move to the
new LibRIFF.
Sidenote for the spec comments: even though they are linked from a site
that explains the WAV format, the document is the (an) overall RIFF spec
from Microsoft. A better source may be used later; the changes to the
header are as minimal as possible.
Previously, all page contents ended up overprinting a single line
over and over for PDFs that used only `\r` as line ending.
This is for example useful for 0000364.pdf.
This is to avoid duplicating the printing logic and so that we can
have an alternative way of printing the result (i.e. for the next
commit that will print without a pathname if no file operands were
provided). This also has us avoid the algorithm checks in the for
loop.
This codepath is separate from the predictor in the TIFF decoder.
The TIFF decoder currently does bits->Color conversion before
processing the predictor. That doesn't fit the PDF model where
filters are processed before converting streams into bitmaps.
If this code here ever grows to handle all cases, maybe we can move
it over to the TIFF decoder and then make it do predictions before
decoding to colors, to share this code.
(TIFF prediction is pretty messy since it's bits-per-pixel-dependent.
PNG prediction is always byte-based, which makes things easier.)
SamplingFactors already has default initializers for its field,
so no need to have an explicit one for the first of the two fields.
No behavior change.
