A few potential error cases were being unwrapped, resulting in a very
small number of crashes. These errors can be safely ignored as the
program cache is non-critical, so this change makes us log the error
and continue rather than panicking.

Currently it's completely unclear at use sites that the getters for `once`
static prefs return the pref value from startup, rather than the current pref
value. (Bugs have been caused by this.) This commit improves things by changing
the getter name to make it clear that the pref value obtained is from startup.
This required changing things within libpref so it distinguishes between the
"base id" (`foo_bar`) and the "full id" (`foo_bar` or
`foo_bar_DoNotUseDirectly` or `foo_bar_AtStartup` or
`foo_bar_AtStartup_DoNotUseDirectly`; the name used depends on the `mirror` and
`do_not_use_directly` values in the YAML definition.) The "full id" is used in
most places, while the "base id" is used for the `GetPrefName_*` and
`GetPrefDefault_*` functions.
(This is a nice demonstration of the benefits of the YAML file, BTW. Making
this change with the old code would have involved adding an entry to every
single pref in StaticPrefList.h.)
The patch also rejigs the comment at the top of StaticPrefList.yaml, to clarify
some things.

This better distinguishes it from the pref name part of the getter, which uses
snake case.

This patch reverts the previous attempted fix for snapping issues
with picture caching, and implements a better solution.
This fixes the main visual issue by ensuring that any fractional
offset in the root transform is accounted for by:
* Offsetting the tile rects by this amount, so that the content
origin is a whole device pixel.
* Invalidating all tiles if the fractional part of the root
transform changes. This is required since it can affect the
snapping logic that WR applies. Fortunately, this occurs
very rarely - Gecko typically has a constant fractional part
for each page.

Minor things to ease the transition to StaticPrefList.yaml.
- Rename apz_touch_drag_enabled() to the correct apz_drag_touch_enabled(), and
media_mwf_low_latency_force_disabled() to the correct
media_wmf_low_latency_force_disabled().
- Change some trailing C-style comments to C++-style comments. This makes life
easier for the script I wrote to convert StaticPrefList.h to
StaticPrefList.yaml, which will be used for the next patch.
- Avoid comments on #define lines, because they aren't handled in the YAML
input.
- Convert a multi-line `#if` condition to a single line, because
Preprocessor.py doesn't handle multi-line conditions.
- Remove one unnecessary `#undef PREF_VALUE` directive.
- Move intl.charset.detector.iso2022jp.allowed to the correct section, so the
YAML processing script won't complain.
- Change an `int` pref to `int32_t`, again so the YAML processing script won't
complain.
- Change OS_OPENBSD to XP_OPENBSD, because the former isn't defined for
preprocessor.py. (It's also only defined in C/C++ when chromium-config.h is
included, which isn't always the case.)

Without CoreAnimation, back-pressure was applied by SwapBuffers: On a
double-buffered NSOpenGLContext which is bound to an NSView, [context flushBuffer]
waits for the previous frame to be finished. With CoreAnimation, the context
is no longer bound to an NSView, and SwapBuffers acts as a regular glFlush.
glFlush on its own does not prevent overproduction.
If we submit GPU work at a faster rate than the GPU can handle, we end up
delaying the window server's GPU work. This can cause the window server to skip
frames. So even if Gecko can produce frames at 60FPS, the window server might
only present those frames at 30FPS, skipping every second frame.

This should ensure that the OOPIF gets painted and attached to the
compositor layer tree before the main part of the test starts. We might
be able to do something more sophisticated like waitForAllPaints or
flushApzRepaints, but it's not trivial because this page loads with an
example.com domain and can't easily access SpecialPowers.

When rendering text in webrender we rasterize glyphs either in local
space at a chosen raster scale, or in device space taking in to
account to text's transform.
We are not able to rasterize glyphs larger than a certain size,
however. So if the device-space font size exceeds this limit, then
currently we force the glyph to be rasterized in local space, at the
untransformed font size. This must then be scaled by the shader when
rendering text, and at high zoom levels this will result in blurry
text.
This change makes it so that rather than rasterizing at the
untransformed font size we rasterize at the font size limit. This will
mean the glyphs are rasterized at a larger size and will therefore
require less scaling, meaning they will appear less blurry.
