[ft] Fix resizing of bitmap fonts
From b94a519aad3d5b50aa6de47ee16ee6a099de9791 Mon Sep 17 00:00:00 2001
Say, you were asking cairo for a font at 200px. For bitmap-only fonts,
cairo was finding the closes strike size and using it. If the strike
was at 20px, well, that's what you were getting. We now scale that 20px
strike by a factor of 10 to get the correct size rendering.
Note that by itself this patch doesn't change much on the Linux desktop.
The reason is that the size you are interested in (eg. 200px) is lost by
fontconfig. When you request a font at 200px, fontconfig returns a font
pattern that says 20px, and so the next layers thing you want a font at
20px. To address that, one also needs a piece of fontconfig config that
puts the 200 back into the pixelsize. Something like this:
<match target="font">
<test name="scalable" mode="eq">
<bool>false</bool>
</test>
<edit name="pixelsize" mode="assign">
<times>
<name>size</name>
<name>dpi</name>
<double>0.0138888888888</double> <!--1/72.-->
</times>
</edit>
</match>
I'm going to try to upstream this config so it will be enabled by
default. The config can be a bit smarter. For example, if
metricshinting is enabled and the size difference is small, we may as
well not scale.
The nice thing about this is that the configuration of whether and when
to scale bitmaps will be done in fontconfig, not cairo / Qt / ... code.

[FT] Prefer downscaling bitmap glyphs to upscaling
From a8f1b456db744e33a10b2301df03528787e5b1ca Mon Sep 17 00:00:00 2001
Say, you have bitmap strikes for sizes 50ppem and 100ppem.
To render at 60ppem, it's much better to downscale the 100ppem
bitmap than upscale 50ppem one. Prefer downscaling.

[ft] Fix wrong assumptions
From e738079302a968b7b1fb9101cd4d92a8887bedce Mon Sep 17 00:00:00 2001
If subpixel rendering is enabled, but FT returns a 8bit gray bitmap
(perhaps because the font has 8bit embedded bitmaps) we were hitting
the assertions because the assumptions made were wrong. Fix up.

[ft] Ensure alignment of bitmaps received from FreeType

When restoring the refresh driver after testing we can arrive at a situation
where a layer has an animation that has yet to start. However, calling
ElementAnimations::GetPositionInIteration with a negative value from the
compositor thread is an error.
This patch detects animations on the compositor thread that are yet-to-start and
skips them when sampling. It also moves the activeAnimations = true line up as
otherwise we would need special logic to wake up the compositor after the delay
has finished.
