Simplify multi-touch state machine code
This is a minor refactoring of the touch tracking in compositor, to simplify the code and prepare for more gesture handling (like pinch to zoom). r? @glennw

When a layer containing an iframe changes, we also need to resize the
root layer of the subpage. This ensures that content from the child
layer tree is masked to the new size.
Fixes#8301.
This is enabled by default on Android, because Glutin currently sends mouse
events instead of touch events on Android. It's also useful for testing on
non-touch platforms.
Instead of always promoting iframes to StackingContexts, integrate them
into the display list. This prevents stacking bugs when
non-stacking-context elements should be drawn on top of iframes.
To accomplish this, we add another step to ordering layer creation,
where LayeredItems in the DisplayList are added to layers described by
the LayerInfo structures collected at the end of the DisplayList.
Unlayered items that follow these layered items are added to
synthesized layers.
Another result of this change is that iframe layers can be positioned
directly at the location of the iframe fragment, eliminating the need
for the SubpageLayerInfo struct entirely.
Iframes are the first type of content treated this way, but this change
opens up the possibility to properly order canvas and all other layered
content that does not create a stacking context.
Fixes#7566.
Fixes#7796.
Add viewport configuration support to the compositor
This allows me to do stuff like this.
Those are two compositors rendered on the same OpenGL context, I need this so I can split windows and render them without getting mad with textures and framebuffers, it will also allow me to render the proper parts of the chrome as different web pages without involving dozens of framebuffers and textures.
If I recall correctly I did talk to @glennw about this on IRC some time ago.
This pull request requires https://github.com/servo/gleam/pull/39 to be merged first tho.

Unify all compositor shutdown code paths into two methods, one which
starts the shutdown and the other that finishes it. This simplifies the
way the compositor shuts down and prevents "leaking" pixmaps when
exiting in uncommon ways.
Remove constellation round trip for subpage mapping in compositor.
This makes use of the new functionality that allows iframes to generate their own pipeline IDs in order to remove any knowledge of subpage ids from the compositor.
(This is the first of several commits removing subpage from parts of servo).

The structure of this function was confusing, so move some parts out into the
caller where they seem like a more natural fit and add documentation of the
functions
This makes use of the new functionality that allows iframes to generate their own pipeline IDs in order to remove any knowledge of subpage ids from the compositor.

Add an option to dump the layer tree, which activates the previously
unused layer tree debugging code. Also improve the output using the
PrintTree struct.
each iframe.
The old code that attempted to do this during layout wasn't able to work
for multiple reasons: it couldn't know where the iframe was going to be
on the page (because of nested iframes), and at the time it was building
the display list for a fragment it couldn't know where that fragment was
going to be in page coordinates.
This patch rewrites that code so that both the sizes and positions of
iframes are determined by the compositor. Layout layerizes all iframes
and marks the iframe layers with the appropriate pipeline and subpage
IDs so that the compositor can place them correctly. This approach is
similar in spirit to Gecko's `RefLayer` infrastructure. The logic that
determines when it is time to take the screenshot for reftests has been
significantly revamped to deal with this change in delegation of
responsibility.
Additionally, this code removes the infrastructure that sends layout
data back to the layout task to be destroyed, since it is now all
thread-safe and can be destroyed on the script task.
The failing tests now fail because of a pre-existing bug related to
intrinsic heights and borders on inline replaced elements. They happened
to pass before because we never rendered the iframes at all, which meant
they never had a chance to draw the red border the tests expect to not
render!
Closes#7377.
Remove 'get_*' on getters as per RFC 0344 on canevas, compositing, devtools, gfx, layout, net, profile, servo and webdriver_server
Hi guys,
I just gave a big pass of RFC-0344 as per issue #6224 .
Pretty much renamed all the get_* fn that were used to fetch values.
I hope I didn't rename too much.
As said in the issue discussion, I didn't touch at the scripts folder so we keep the unsafe ones pretty explicit.
I've ran the whole pass of test, everything seems to be still working right :).
Please give feedback on this PR.
Thanks for looking into it.
