Part of this patch got lost in a rebase, this completes it.
Untranslate fixed position layers when doing async scrolling so that they don't
jump about as content re-renders them in the correct place.
Skia uses a value of 0.5, however using such a high value causes some reftest failures.
Switch to 0.3 because we can do that without changing the reftests too much. We
can still use a higher value if we need to later. This should give us sqrt(3)
reduction in the number of segments.

This fixes the tearing we get on OS X with OpenGL layers.
It does cause us to occasionally block waiting for vsync.
This isn't ideal but I think it's better than tearing.
OMTC should help us remove this wait.

CGContextSetTextMatrix has behaviour that depends on the text
drawing mode. We want consistency so avoid CGContextSetTextMatrix.

This takes a trick from skia to go faster. For now, it's only
used on non-NEON devices.

Unfortunately, in-process plugins using OpenGL break the assumption made by these patches, that the current GL context is only changed by GLContext::MakeCurrent. Another issue, regardless of in-process, is that our host-side code in nsCoreAnimationSupport.mm uses direct CGL calls, bypassing GLContext.
This will allows us to scale and repeat in a single pass instead
of doing it in two.

This takes the bilinear interpolation code from Skia. It
uses 4 bits of precision instead of 8. This lets it interpolate
two components at a time because the results fit in 16 bits.
The lower precision code is only used in the fallback code
and not in any of the specialized code for NEON. This means
pixman gives different results depending on the cpu which isn't
great. However, this was easiest and the NEON code doesn't
gain as much from using lower precision.
Skia actually uses even lower interpolation when working with
565 but that's harder to plug in right now, and this gives
a reasonable improvement.
These may need some tuning to get right, but should be an improvement over
just disabling bilinear for backgrounds.
It also expectedly regresses tcheckerboard & tcheck2 because we're now
using bilinear when we were using nearest before.

When the layer size changed, reused tiles that then fell out of the layer area
would be incorrectly rendered. Fix this by deriving the rendered content area
from set display-ports and correctly invalidating when harvesting tiles, and
clipping when drawing them.

It seems like we sometimes end up using EXTEND_NONE unintentionally, this is
likely caused by different rounding between cairo and pixman. Pixman already
does a similar reduction to EXTEND_NONE so there's not point in duplicating it
here.

Bug 748718 tried to fix masking of the checkerboard layer, but incorrectly
calculated the values for the right and bottom sides of the page, causing
less masking to occur than should happen.
It also possibly broke single-colour layer drawing (though I'm not sure this
worked previously), which this fixes by clearing to the page colour instead of
generating and drawing a texture for it.
It is possible for the content that layers represent to change size, causing
tiles to be reused where they shouldn't. Make sure that tiles that are outside
of content bounds are not drawn, and that they get evicted when harvesting
tiles.
Rather than discarding uploaded tiles once they fall outside of the valid
region, shuffle them off into a separate tile-store with all the metadata they
need to render them, and render them in the areas that our current valid
region doesn't cover in TiledThebesLayerOGL::RenderLayer.
