This fixes the positioning of underlines set on a block or its ancestor
when drawn on children of a block that have a vertical-align !=
baseline.
The lazy computation is done all at once for all children of a block to
avoid O(N^2) searches for the line containing a frame.
On Windows, when selecting a word by long pressing, extra spaces after
the word will also be selected. To solve this problem, I redesign the
test cases by comparing the target content with the selected content
directly while ignoring spaces at certain test cases. I believe it's
easier to understand and less error-prone than the old
replace-selected-content-and-compare way.
I added a new method SelectionManager.selected_content() to make it
easier to get the current selected text.
Use PCompositor::NotifyChildCreated which was ill-defined for
cross-process case.
Assume that for all LayerTrees managed by a CrossProcessCompositorParent
all share the same CompositorParent.
This patch removes the check that skipped queueing events for animations
without keyframes since the spec indicates such animations should dispatch
events.
There is a further correctness fix here for the case where a keyframes rule
is modified using the CSSOM so that it becomes empty. Previously when we
came to create the new animation rules we would end up setting
ElementAnimations::mNeedRefreshes to false since we check if the keyframes
rule is empty and if it is we would skip all further processing (including
setting mNeedsRefreshes).
That means that:
(a) We may end up unregistering from the refresh observer so we would never
dispatch the end event for such an animation.
(b) If the animation was running on the compositor we may never remove it from
the compositor or may not do it in a timely fashion.
To fix both these problems, this patch removes the check for an empty keyframes
rule so that mNeedsRefreshes is set in this case.
This patch adjusts the tests for transform transitions that run on the
compositor to handle transitions that begin with a non-invertible transform.
In this case the first sample at the start of the animation won't create
a layer because in nsDisplayTransform::BuildLayer
/ FrameLayerBuilder::BuildContainerLayerFor we'll skip creating the layer once
we notice the equivalent matrix is singular.
In this patch we detect that case and force an extra sample betwee 0 and 200s at
100s. This means the layer will be created at t=100s and be available for
querying at the next sample.
Similar issues could occur, for example, if the transforms at both t=0s
and t=100s are not invertible but currently that doesn't occur. We can add
handling for that if and when it becomes necessary.
This patch takes the existing tests for transitions running on the compositor
and makes them re-use the same test utility methods as used for testing CSS
Animations that run on the compositor. This means these tests now also check
that the transition is in fact running on the compositor when it is expected to.
It seems the big_omta_round_error is no longer needed so I've removed that.
The test that begins with "skew(45deg, 45deg)" currently fails so it is skipped
here. This is addressed in the next patch in the series.
This patch simply re-arranges the order of arguments to omta_is_approx so that
the delta sits along side the values being compared.
This, I think, makes more sense and also is more consistent when converting
tests from test_animations.html to test_animations_omta.html since the
"RunningOn" parameter is consistently inserted in the second-to-last position
just before the description for both omta_is and omta_is_approx.
This patch removes the line from new_div that forced a style flush. This was
very confusing because:
* It behaved differently to new_div in test_animations.html so copying tests
over was more complex (particularly when registering for events is involved).
* It meant after setting up initial style using new_div you could just call
waitForPaints but if you updated style using elem.style you'd need to call
waitForPaintsFlushed.
In adjusting test_animations_omta.html we are able to simplify the tests
somewhat. This patch also adds a few additional checks that waiting to update
the compositor does not produce different results.
This patch moves some test utility methods from test_animations_omta.html to
animation_utils.js. It also renames addAsyncTest to addAsyncAnimTest and
likewise for a few other methods.
Add marionette test cases for touch caret feature in bug 924692. Test
cases cover <input>, <textarea>, and contenteditable elements with
touch caret enabled and disabled.
Enlarge touch caret expiration time to 60 seconds to avoid intermittent
test failures in test cases which need to move touch caret.
Thanks Phoebe Chang <natsuki011077@gmail.com> for the WIP patch.
Thanks C.J. Ku <cku@mozilla.com> for various suggestions.

* Extract those caret manipulating functions in test_touchcaret.py to
selection.py, and generalize them for manipulating selection.
* Use SelectionManager in test_touchcaret.py.
* Remove unneeded </input> from test_touchcaret.html.

In addition to moving the code, this patch also:
* changes the square character from U+25AA to U+25FE to match the spec
* changes all the generating functions from using append to using assign
* removes negative handling from CJKIdeographicToText since it is no longer used there
* fixes indentation and naming conventions
* changes buffer size in DecimalToText

For touch events generated by marionette, the touch id is not started
from 0. Therefore, instead of getting the event position of touch id 0
directly in HandleTouchDownEvent(), we should loop over all the touch
ids to get their positions.
This patch adjusts GetComputedTimingAt to set the time fraction and current
iteration fields of the output computed timing correctly for animations with
zero iteration duration. Care must be taken to handle cases such as animations
that have zero duration but repeat infinitely.
The code is significantly re-arranged to more closely align with the naming and
algorithms defined in Web Animations.
A couple of tests in test_animations.html have been tweaked to account for
floating-point error. This is not because the new code is less precise but
actually the opposite. These tests fall on the transition point of step-timing
functions. The new code uses the closest possible floating-point representation
of these times which happens to cause them to fall on the opposite side of the
transition point.
For example, in evaluating a point 3s into a reversed interval the old code
would give us an intermediate time fraction of:
0.29999999999999982
When we reverse that by subtracting from 1.0 we get: 0.70000000000000018
With the code in this patch we get an intermediate time fraction of:
0.29999999999999999
When we reverse that by subtracting from 1.0 we get: 0.69999999999999996
Hence we fall on the opposite side of the transition boundary.
This patch also makes ElementAnimation::ActiveDuration a static method that
takes timing parameters as an argument. This is so that this method can be
used within ElementAnimations::GetComputedTimingAt (a static method) in a
future patch.
We could also make ActiveDuration() a method of AnimationTiming. I suspect
this logic belongs together in ElementAnimation however.
In a future patch we could also add the active duration to the ComputedTiming
struct which would simplify the only other place this is currently used
which is ElementAnimations::GetEventsAt.
