Since we cannot move away from mozilla::IsNegative to std::signbit because the
first one doesn't accept a NaN we should transform our function to use std implementation.

When upgrading the NDK to r23, the wrench builds for android fail
because cargo apk starts adding flags to the cargo rustc call it does,
and that's not compatible with the wrench crate having both a lib and a
bin target.

As cargo apk only packages the lib in the apk, we can just be explicit
and build the library only.

Right now we fire glxtest on every Firefox start, even if we going to update, restart or ping running remote instance.
When we're running on system with broken/unstable gfx drivers (drivers/glx freezes or crashes) every such action is delayed or coredumps are generated on systems.

In this patch we launch glx test proces later if we know we need it.

Bug 1823516: Adjust text-input-block-size.optional.html to use Ahem with a nice font-size, for predictable whole-number baselines and sizing. r=ntim

Before this patch, Firefox fails this test's expectations on Linux, with a 1px
sizing discrepancy between the input element in a vertical writing-mode
vs. horizontal.

That discrepancy is almost certainly due to the difference in baselines
(central vs. ideographic) in vertical vs. horizontal writing-modes, and the
fact that pixel-snapping that baseline might produce a +/-1px difference in
block-position and block-size of the line, inside the form-field.

This patch changes the test to use the Ahem font with a font-size of 30px,
which should have a whole-pixel-valued central as well as ideographic baseline;
so no pixel-snapping should be necessary, and the input element's size should
be be consistent, just as the test expects it to be.

This patch also makes one non-functional change, to explicitly declare the
charset as UTF-8, per WPT best-practices from
http://web-platform-tests.org/writing-tests/general-guidelines.html#character-encoding

Bug 1737725 - Ensure hit-testing never observes scroll offsets that don't have async deltas applies. r=hiro,gw

When a new scene is swapped in on the render backend thread, its
scroll frames have scroll offsets that come from the main thread
and do not reflect async scroll deltas until such deltas are
sampled from APZ.

It's possible for hit-testing to observe the scene in this
temporary state, potentially leading to incorrect hit-test results.

To avoid this, save the async offsets from the previous scene
and apply them to the new scene until we can sample proper offsets
from APZ.
