 * Avoids having a bunch of per-platform implementations.
 * We don't need to actually get graphics info for it to work.

Bug 1809738 - Avoid using scissor rect when clearing render targets on Mali GPUs. r=gfx-reviewers,lsalzman

We currently set a scissor rect when clearing render targets, as this
was measured to be a performance win on some GPUs. On Mali, however,
it is better to perform a full, non-scissored clear of a render target
immediately after binding it, as this allows the driver to omit
reading the previous contents in to tile memory. This patch makes it
so that by default we perform the non-scissored clear on Mali, and
retain the scissor on all other GPUs. The existing
enable_clear_scissor option can be used by the embedder to override
the default value.

Of particular note, this massively improves the performance of twitter
on Mali G710 (eg Pixel 7), where the blur backdrop-filter uses several
intermediate render targets and the scissored clear causes noticable
stutter.

This removes the capability of having differently-sized vertical and
horizontal scrollbars (which is only potentially used in windows, and in
practice almost-never used). For that case, we choose the larger of
vertical/horizontal scrollbar sizes.

This is in order to be able to realistically expose the scrollbar size
to CSS, see blocked bug.

We make RecomputeScrollbarParams the central place where each scrollbar
style decides its sizes, and make GetDPIRatioForScrollbarPart handle the
cocoa special-case of scaling to 1 or 2, but nothing else.

Skia upstream removed deprecated clip ops that could be used to replace
the clipping stack and bypass clips. We shouldn't really need to do this
anymore, as we can work around it just using public APIs.

The only SkCanvas operation that allows us to bypass clipping is
writePixels, which still allows us to implement CopySurface/putImageData.

Other instances where we were using the replace op for DrawTargetWebgl
layering support can just be worked around by creating a separate
DrawTargetSkia pointing to the same pixel data, but on which no clipping
or transforms are applied so that we can freely do drawing operations
on it to the base layer pixel data regardless of any user-applied clipping.

Bug 1363454 - Create a pref to list icon font families that should be used even when use_document_fonts=0, overriding the browser's font prefs. r=emilio,dholbert

Some widely-used icon fonts use ligature rules to replace icon names such as "volume_up"
or "down_arrow" with icon glyphs. If the site is designed to use such a font, but the user
disables document fonts and we use our default Latin font instead, the underlying text will
be rendered instead of the intended icon.

To enable such fonts to continue to work, we provide a list of known ligature-icon fonts
and allow them to be used even when the document-fonts setting is disabled.

This patch adds most of the underlying infrastructure for a new
tiled (previously: segmented) rendering path to webrender. It is
initially used only by simple (non-masked) rectangles. Follow
up patches will extend this first to all rectangles and then
porting other primitives to use this new rendering path.

The new primitive is encoded in the command buffer structure,
which allows efficiently encoding arbitrary sets of commands
to be read by the batching code. The batching code for this
primitive is much simpler, and should be consistent and shared
when other primitives are ported to use this path.

Tiling is handled during the prepare pass per-primitive. It can
support edge AA tiles, different regions for clip-mask corners
(to be added in a follow up), and uniform tiling for the inner
section of the primitive (e.g. for tiled image masks).

It adds specific support for edge anti-aliasing to be considered
as part of the tiling configuration for a primitive. This both
improves performance of rotated but otherwise opaque primitives
and allows additional functionality we don't currently support
(such as applying AA along one edge of a 2d but subpixel aligned
primitive). Since SWGL provides native AA support, the patches
take account of that, and avoid the vertex shader work and extra
edge primitives when SWGL is enabled.

Follow up patches will:
 - Add clip-mask support to new rendering path
 - Port other primitives to new rendering path
 - Add SWGL shader fast-paths where profiling indicates it makes sense to
 - Remove old segment / mask rendering paths once no longer used

Other minor changes included as part of this patch:
 - Pack TransformPaletteId in 24 bits instead of 32, for better instance struct packing
 - Support prepare pass appending multiple command buffer instructions per primitive

The function ANativeWindow_fromSurface() takes a jobject that is
supposed to be a Surface. Prior to bug 1706656 GeckoSurface was a
subclass of Surface, meaning we passed the correct type. However,
GeckoSurface no longer derives from Surface meaning we hit this JNI

To fix this, call GeckoSurface->GetSurface() to get the underlying
Surface object.

Note that this code path is only active if the user has modified the
pref gfx.use-surfacetexture-textures. So although the volume is high,
it appears to be limited to a small number of users.

Bug 1811160 - Disable out-of-process WebGL and accelerated canvas when GPU process does not exists on android r=gfx-reviewers,lsalzman

On Android, GPU process exists by default. When GPU process does not exist, an error should disable GPU process.

On Android, WebGL handling process could easily crash. The crash could trigger disable GPU process. Current out-of-process WebGL implementation creates WebGLParent in parent process. Then a crash in parent process could be triggered by WebGL. Then it seems better to disable out-of-process WebGL when GPU process does not exist.

And it seems also better to disable accelerated canvas, since it uses WebGL for acceleration.

+ Add gfx.color_management.rec709_gamma_as_srgb:true. :'(

In particular, rec709(16/255) -> srgb(31/255). Even though it's
technically correct, it's practically-speaking incorrect, since that's
not what Chrome does, nor what the web expected for years and years.

In practice, basically everyone expects gamma to just be completely
ignored.

What people expect:
* Pretend gamut is srgb(==rec709), but stretch this naively for the
  display. If you have a display-p3-gamut display, srgb:0.5 expects to
  be displayed as display:0.5, which will be display-p3:0.5 to the eyes.
* Pretend all content gammas (TFs) are srgb(!=rec790), and then bitcast this
  naively for the display. E.g. rec709(16/255) should
  display the same as srgb(16/255), not srgb(31/255). (Note: display-p3
  uses srgb gamma) But if your display has e.g. gamma=3.0, don't
  convert or compensate.

This is a formalization of what you get when you spend decades ignoring
color management, and people build things based on behavior-in-practice,
not behavior-in-theory.

Also:
+ gfx.color_management.native_srgb:true for Windows, so we don't use the
  display color profile, which no one else does.
+ Add rec2020_gamma_as_rec709, so we have a path towards maybe having
  rec2020 use its correct transfer function, rather than srgb (like
  rec709).
