Altivec code was previously uncompilable, and the altivec accelerations
also could not be disabled with a build flag or env variable, leading
to pale moon not being buildable on any altivec supported CPU ( all
PPC CPUs ever almost ). Why? I don't know, 'inline' in C is cursed
and making it static makes it significantly less so.

- Don't check STAT designAxisSize if the designAxisCount is zero.
- Avoid potential arithmetic overflow during Buffer read operations.
- Use more careful range checks in STAT parsing.
A few dozen Emojis use otherwise general font characters in the lower codepages.
Luckily, the Emoji codepages always include either a VS16 or KeyCap suffix.
Detection of Emoji Components, for use as suffixes of TextDefault.
Detection of Non-Presentation Emojis as TextDefault.
Detection of all Extended Pictographics as EmojiDefault.
This ensures we don't scale the underlying size of the layer beyond what
is close to the current display size. When box shadows get much larger
than this, they start taking so much time to render that successive
frames grow in scale too fast for any inter-frame reuse to be possible.
With this, we avoid that and no longer get crushed by re-rendering
gigantic box shadows every single frame.
See BZ 1383825
A second template parameter 'F' was previously added to SizeTyped, but
was not correspondingly added to the argument passed for the 'Sub'
parameter of BaseSize.
There's considerable cost associated with creating HWA draw targets
which would negate and regress the performance won by it if used for
too small targets (like small spans of text).
This only uses HWA if >= 8K SurfaceAllocationSize to balance HWA draw
target cost with box blur cost.
Only blur one quadrant of a box-shadow and mirror it to the other quadrants.
This applies only if the corners are symmetrical (square corners or equal
corner radii) otherwise we'll fall back to the old method.
Mozilla found a bug in their initial implementation, causing paused WebM videos with alpha to become totally transparent if hardware acceleration is disabled. Straight port of the Firefox 54 fix.
Ref: BZ 1332952
Another requirement to have transparency in videos. Straight port of Firefox 53 implementation, save for some oddities relating to needing to put uint8_t instead of uint8 in yuv_convert to get this to compile.

Sets the pref default to true and also add conneg entry for images
if jxl support is built.
Additionally, ifdefs the GfxPref to only observe when jxl is built.
Vim control lines were re-introduced or not entirely cleaned up.
This nukes them again.
Removing from embedding, extensions, gfx, hal, ipc, layout, mailnews,
media and memory. More to come.
