This updates webrender to include the webgl related changes
needed for this patch. There was an additional commit in
webrender before these landed, so also copy the shaders
for that change across. There is an interface change to
webrender push_image. For now, just pass zero, which is a
no-op to this function. A follow up commit will introduce
the servo specific changes to use this new interface.
sizes if the block formatting contexts have negative margins.
The heuristics that determine how and whether floats flow into the
margins are not valid in that case.
Closes#13299.
Create separate layout trace file for each reflow
<!-- Please describe your changes on the following line: -->
Currently only the layout trace from the last reflow is dumped to the file. But the interesting reflow may not be the last one. So we are dumping each of them with filename `layout_trace-{generation}.json`.
This will be used by a GUI viewer to visualize the layout process, which I will check-in later.

Move collapse through margin to the top of block flow
<!-- Please describe your changes on the following line: -->
Based on the spec, a collapse through box should be put on the top edge of the flow. This fixed ~110 reftests

Handle row borders in border collapsing logic.
<!-- Please describe your changes on the following line: -->
Handle table row border when collapsing borders for a table row. The row border is combined with the cell's border using the already implemented conflict resolution logic.
This is a screenshot of the following test:
```html
<!doctype html>
<html><body>
<style>
table {
border-collapse: collapse;
}
tr {
border: 1px solid black;
}
</style>
<table>
<tr><td>Lorem</td><td>Ipsum</td><td>Sit</td><td>Dolor</td></tr>
<tr><td>Lorem</td><td>Ipsum</td><td>Sit</td><td>Dolor</td></tr>
<tr><td>Lorem</td><td>Ipsum</td><td>Sit</td><td>Dolor</td></tr>
<tr><td>Lorem</td><td>Ipsum</td><td>Sit</td><td>Dolor</td></tr>
</table>
</body>
</html>
```
<img src="https://dl.dropboxusercontent.com/u/10962672/Screenshots%20Servo/servo_tr_border_collapse.png"/>
The top border is missing, but I think that's a different bug, since it also does not show up when the border is in the cells, and not the rows. Also, when debugging the border collapsing structures, they seem ok (the top border seems to be there). I can look at that bug in a separate issue (or in this one too if you prefer).

Fixed layout flow tree JSON serialization
<!-- Please describe your changes on the following line: -->
The second argument for the `emit_struct()` is the number of fields, if given `0`, the output JSON will always be empty.
This is used in `./mach run -d -Z trace-layout https://servo.org`, which will dump the layout flow tree into a `layout_trace.json` file for debugging.
This also unblocks https://github.com/servo/servo/issues/12675

Inline reconstruct#12602
<!-- Please describe your changes on the following line: -->
This PR fixes two different issues:
1) In non-incremental layout mode if the inline node hasn't changes - the style pass was skipped, that leads to the corresponding ConstructionResult was not produced. When the parent was rebuilt, the child without the ConstructionResult was omited.
2) When the opacity was changed (or other style change, causing only repaint) for image (and others, producing only ConstructionItem) the damage is calculated only from children's flows, not from individual fragments. So for now, let's pretend we've newly constructed the ConstructionItem and thus need to rebuild the parent's flow.

Fix wrong calculation of inline element's block size
Border, padding and margin properties' top and bottom values of inline elements were affecting the element's height. It shouldn't affect it normally. Fixed it and added a test.
