The code in ComputeSuitableScaleForAnimation feeds its double-based
computation results into GetSuitableScale, which takes and returns
floats. Also the double-based computation that it's doing involves
calling UpdateMinMaxScale a bunch which explicitly uses the float
variant of std::min and std::max. And all of this is used from
ChooseScaleAndSetTransform which does other things like call a
"RoundToFloatPrecision" function, and casts the final values to
floats before setting the layer's prescale. So let's just use
floats all the way through.

We pass in `const {Blur,Gradient}CacheKey&` to these functions. There's
no need to copy the cache keys here; we can just Move() the existing
objects in instead. Doing this saves unnecessary allocations and/or
refcounting.
The core of this change is in gfxContext.*:
- change gfxContext::CurrentMatrix() and gfxContext::SetMatrix() to
return and take a Matrix respectively, instead of converting to
and from a gfxMatrix (which uses doubles). These functions therefore
will now match the native representation of the transform in gfxContext.
- add two new functions CurrentMatrixDouble() and SetMatrixDouble() that
do what the old CurrentMatrix() and SetMatrix() used to do, i.e.
convert between the float matrix and the double matrix.
The rest of the change is just updating the call sites to avoid round-
tripping between floats and doubles where possible. Call sites that are
hard to fix are migrated to the new XXXDouble functions which preserves
the existing behaviour.

This case is hit by hovering over menu items, so the optimization is somewhat worthwhile.
As a side-effect, not causing reflows also avoids a XUL <select> popup positioning bug.

This removes non-"gfx.*" prefs defined in gfxPrefs.h, but the generated gfxPrefs
properties are not accessed anywhere in the code base:
* apz.overscroll.spring_friction
* apz.overscroll.stop_velocity_threshold
* apz.overscroll.stretch_factor
* dom.w3c_touch_events.enabled - this pref is accessed in other places, but not through
gfxPrefs::TouchEventsEnabled().
* general.smoothScroll.lines
* general.smoothScroll.pixels
* layers.composer2d.enabled
* layers.stereo-video.enabled

The following prefs are removed because they are defined in gfxPrefs, but the
resulting gfxPrefs property is used at all.
* gfx.SurfaceTexture.detach.enabled
* gfx.touch.resample.*
* gfx.screen-mirroring.enabled

And remove unreachable code after MOZ_CRASH_UNSAFE_OOL().
MOZ_CRASH_UNSAFE_OOL causes data collection because crash strings are annotated to crash-stats and are publicly visible. Firefox data stewards must do data review on usages of this macro. However, all the crash strings this patch collects with MOZ_CRASH_UNSAFE_OOL are already collected with NS_RUNTIMEABORT.

Add a new TextureClientData type, AndroidNativeWindowTextureData,
backed by a SurfaceTexture in single-buffer mode. It uses the
NativeWindow API, which provides producer-side access to the buffer.
This provides a DrawTarget which can be used to paint directly in to
the SurfaceTexture, which can then be composited using a SurfaceTextureHost.
Due to API restrictions it is not possible to read from a NativeWindow
while the corresponding SurfaceTexture has ownership of the
buffer. TiledContentClient now handles that by painting the additional
region that it cannot copy from the front buffer, if required.
