There is a bug on Adreno GPUs where glBlitFramebuffers always writes
to the 0th layer of a texture array, regardless of which layer is
actually attached to the draw framebuffer.
With picture caching enabled on webrender, the cached pictures were
all being drawn to the 0th layer of the picture cache texture array,
leaving the other layers blank. This was resulting in the wrong
content being drawn on one tile of the screen, and the rest being
black.
This works around this by blitting to an intermediate renderbuffer,
then using glCopyTexSubImage3D to copy from the renderbuffer to the
correct texture layer.

Same for blit_render_target_invert_y(). Make them wrappers around the
private function blit_render_target_impl(), which uses the currently
bound read and draw targets as before.

We always pass the same set of types so it seems simpler to just look it up
within the function itself.

EGLConfig could be get from GLContextEGL. It is better to use it than re-creating EGLConfig.

We can get back the fancy flag syntax as soon as we get C++17 inline variables,
which I sent an email to dev-platform@ about, with no reply.

This lets us restrict the size of the mask surface that we allocate
to the destination tile size. This gives a large performance
improvement.
It also includes some miscelanous fixes to the CreateClippedDrawTarget
code path.

DTO = DrawTargetOffset = (-Origin.x, -Origin.y)
CTM = CurrentTransform
MASKT = MaskTransform = Inv(CurrentTransform)
MASKO = MaskOffset = (GetRect().x, GetRect().y)
The transform to device space is:
MASKT * CTM * DTO
Currently we do:
MASKT = MASKT * MASKO
Which gives us MASKT * MASKO * CTM * DTO. This works fine if there's no scale but
will not properly cancel out if there is.
I believe we want:
MASKO * MASKT * CTM * DTO
To get this we need to preTranslate instead of postTranslate.

The way we control APZ zooming in WebRender is by inserting an animation
property placeholder on a WR stacking context, and then having APZ
update the animation transform value with the proper matrix at composite
time.
Previously, the stacking context being used was the rootmost
stacking context in the content process. However this doesn't work for
zoomable content in the UI process (e.g. about:support), and after
recent changes, also wraps display items that should not be affected by
zoom (e.g. scrollbars or the background color item).
This patch moves the animation property placeholder so that it
corresponds to the newly added nsDisplayAsyncZoom display item, which
corrects both of the above problems and is conceptually in line with the
desired behaviour.

Remove the intern_types module in favor of the associated Internable types that we already have.
The only bit of magic I had to do is around serialization bounds, and it's nicely isolated.

A picture can have its own unique clip which was not considered by its
children when calculating their visible rects. As a result, if a picture
clips its primitive rect for snapping purposes, it may produce a
different snapping offset than expected. We should instead just snap to
the primitive rect itself for the picture, since it is the union of the
visible rects that we snapped to for the children.

Other mobile browsers disallow browser-based pinch zooming when the
first touchstart is preventDefaulted, even if the second one is not. We
allowed pinch zooming in that scenario. This patch makes it so that if
the first touchstart is preventDefaulted, then subsequent touchstart
events are also preventDefaulted, which brings our behaviour in line
with that of other browsers.
