This patch reverts the previous attempted fix for snapping issues
with picture caching, and implements a better solution.
This fixes the main visual issue by ensuring that any fractional
offset in the root transform is accounted for by:
* Offsetting the tile rects by this amount, so that the content
origin is a whole device pixel.
* Invalidating all tiles if the fractional part of the root
transform changes. This is required since it can affect the
snapping logic that WR applies. Fortunately, this occurs
very rarely - Gecko typically has a constant fractional part
for each page.

Without CoreAnimation, back-pressure was applied by SwapBuffers: On a
double-buffered NSOpenGLContext which is bound to an NSView, [context flushBuffer]
waits for the previous frame to be finished. With CoreAnimation, the context
is no longer bound to an NSView, and SwapBuffers acts as a regular glFlush.
glFlush on its own does not prevent overproduction.
If we submit GPU work at a faster rate than the GPU can handle, we end up
delaying the window server's GPU work. This can cause the window server to skip
frames. So even if Gecko can produce frames at 60FPS, the window server might
only present those frames at 30FPS, skipping every second frame.

RenderTargetOGL::Bind on mWindowRenderTarget needs to bind the default framebuffer, not framebuffer 0.

This should ensure that the OOPIF gets painted and attached to the
compositor layer tree before the main part of the test starts. We might
be able to do something more sophisticated like waitForAllPaints or
flushApzRepaints, but it's not trivial because this page loads with an
example.com domain and can't easily access SpecialPowers.

When rendering text in webrender we rasterize glyphs either in local
space at a chosen raster scale, or in device space taking in to
account to text's transform.
We are not able to rasterize glyphs larger than a certain size,
however. So if the device-space font size exceeds this limit, then
currently we force the glyph to be rasterized in local space, at the
untransformed font size. This must then be scaled by the shader when
rendering text, and at high zoom levels this will result in blurry
text.
This change makes it so that rather than rasterizing at the
untransformed font size we rasterize at the font size limit. This will
mean the glyphs are rasterized at a larger size and will therefore
require less scaling, meaning they will appear less blurry.
