First patch in of series that will rearrange the layout of the glyph instance attributes so that it matches brush instances.
This will be needed to add a unified shader that can render the most common alpha pass primitives, including text.

…rce_address. r=gw

This user_data field is currently only used as an address for some shader-specific resource in the gpu cache. We can always rename it back to something generic if we ever need to use the bits differently in other shaders in the future.

The glyph pixel space in which we rasterized glyphs differed from how we
rendered the rasterized glyphs in the shader. They need to be in
agreement because the glyph subpixel offset selected during
rasterization depends on it. This patch should make the paths consistent
with each other.

Additionally, during animations, we now snap the reference frame
relative offset ignoring the impact of any animated transforms. This
helps with minimizing glyph wiggling during the transition.

Invalidate_rendered_frame expects full rendering in next WR rendering. Then when invalidate_rendered_frame is requested, we need to request force redraw. Otherwise, SwapChain might skip present call during partial present.

…t occluded r=nical

Tiles that are occluded are generally never seen, or only seen
occasionally. To reduce the number of compositor surfaces:

 * Defer native surface allocation until after occlusion culling occurs.
 * If a tile has a native surface, then becomes occluded, drop the surface.

With this scheme, the number of unused native surfaces will always be 0
on a page that doesn't have scrolling. For a page that has a scrollable
region, there will be a small number of unused tiles retained. The unused
tiles are those that are (a) not occluded (b) not currently visible (c) are
in the display port. We retain these for a small amount of time in case
they get scrolled back on screen.

This makes the allocation patterns for native surfaces match the way
that picture cache surfaces are allocated for simple compositing mode.

Whilst pinch zooming, every picture cache tile gets completely
invalidated every frame. It is therefore a waste of memory bandwidth
to render in to picture cache tiles then composite those to the
screen. This change dynamically disables picture caching for frames in
which we are pinch zooming. The exception is if we are using a native
compositor, in which case picture caching will remain enabled, because
it relies on picture caching to work, and does not waste memory
bandwidth.
