33316ce168 stage: Check coordinate validity in do_pick()
We do some argument validation inside _clutter_stage_do_pick(), which is
the internal version of clutter_stage_get_actor_at_pos(), but we don't
do coordinate space validation, and instead we rely on call sites doing
the right thing.

We should, instead, remove the argument validation from the internal
function, which is pointless and against the coding practices, but do
coordinate space validation internally.

a2551dfa60 ClutterStage: Don't add empty actors to the stage clip
Currently, if an actor with an empty paint volume is queued for redraw, it
will union in the box +0+0x1x1 to the stage clip bounds - avoid that
by special casing empty paint volumes.

705640367a Use the non-deprecated Cogl clipping API
Cogl 1.18 deprecated the global clipping API in favour of the
per-framebuffer one, but since we're using the 2.0 API internally we
don't have access to the deprecated symbols any more.

This is pretty much a mechanical port for all the places where we're
still using the old 1.x API.

a427c120c2 stage: Remove the pick buffer caching
Since the journal is flushed on context switches, trying to use a cached
buffer means that we will use glReadPixels when picking, which isn't what
we want. Instead, always use a clipped draw, and remove the logic for
caching the pick buffer.

46c22de01e stage: Destroy all children when we dispose
Destroying an actor is supposed to destroy all of its children, so
it makes sense to reason that destroying the stage should destroy all
of its children, too.

Unfortunately, it seems that the stage removed all of its children
without destroying them before chaining up to what would destroy all
of its children, for whatever reason. Change this to a destroy so
resources get cleaned up.

0d0cb13c8d stage: Adjust drawing to include the window scaling factor
In order to transparently support high DPI density displays, we must
maintain all coordinates and sizes exactly as they are now — but draw
them on a surface that is scaled up by a certain factor. In order to
do that we have to change the viewport and initial transformation
matrix so that they are scaled up by the same factor.

d061a47573 stage: Add a paint callback
The ClutterActor::paint signal is deprecated, and connecting to it even
to get notifications will disable clipped redraws because of violations
of the paint volume.

The only actual valid use case for notifications of a successful frame
is on the ClutterStage, so we should add new (experimental) API for it,
so that users can actually subscribe to it — at least if you're writing
a compositor.

Shoving a signal in a performance critical path is not an option, and
I'm not sure I want to commit to an API like this yet. I reserve the
right to revisit this decision in the future.

b248941af5 Add clutter_stage_set_sync_delay()
New experimental API is added to allow changing the way that redraws
are timed for a stage to include a "sync delay" - a period after
the vertical blanking period where Clutter simply waits for updates.

In detail, the algorithm is that when the master clock is restarted
after drawing a frame (in the case where there are timelines running)
or started fresh in response to a queued redraw or relayout, the
start is scheduled at the next sync point (sync_delay ms after the
predicted vblank period) rather than done immediately.

b9ad93ad8d stage-cogl: Reuse backbuffer contents
Use the buffer_age extension when available to recycle backbuffer contents
instead of blitting from the back to front buffer when doing clipped redraws.

The picking is now done in a pixel that is going to be repaired during the next
redraw cycle for non static scences.

This should improve performance and avoid tearing.

60f20e8a7e stage-window: make it possible to damage the back buffer
This allows us to report to the backend that the stage's back buffer has been trashed
while handling picking. If the backend is keeping track of the contents of back buffers
so it can minimize how much of the stage is redrawn then it needs to know when we do pick
renders so it can invalidate the back buffer.

3398f3acdf stage: Normalize key focus setting
We often mean that when key_focus == NULL, it's assumed to be on the
stage, and clutter_stage_get_key_focus() reflects this. We also do a
lot of check around the lines of key_focus == NULL instead of also
checking for the stage, so make sure to normalize it so that explicitly
grabbing the stage's key focus will not change our behaviour.

d6a0f7eb61 input-device: don't reset a device's stage until all touch points are gone
803b3bafb6 introduced a new issue for
multi touch events.

In the case where 2 touch events for 2 different touch points are
processed in the same iteration, a call to
_clutter_stage_remove_device() when processing the first event will
remove the stage setting of the InputDevice. That means Clutter will
skip the second event, because it can't find a stage to which relate
the event, so no related actor and so no emission.

To fix this we move the _clutter_stage_(add/remove)_device() calls
into the input device. This way the input device can find out exactly
when to call these functions (i.e. when no touch point were previously
active or when no touch point remain active).

e2564dd265 Deprecate ClutterCairoTexture
The ClutterCanvas content implementation should be used instead, to
avoid stringing along the ClutterTexture API and implementation.

This change requires some minor surgery, as the deprecated section
already contains an header for the previously deprecated methods; plus,
we don't want to deprecate clutter_cairo_set_source_color(). This means
creating a new header to be used for Cairo-related API.

c9a81f035e Don't use any GL types or defines in Clutter
Some of the Clutter code was using GL types for the primitive types
such as GLint and GLubyte and then passing these to Cogl. This doesn't
make much sense because the Cogl functions directly take native C
types. This patch just replaces them with either a native C type or a
glib type.

Some of the cogl conformance tests are trying to directly call GL for
example to test creating a foreign texture. These tests have been
changed to manually define the GL enum values instead of relying on a
GL header to define them.

This is necessary because Cogl may soon stop including a GL header
from its public headers.

4330f45d05 Override Container inside ClutterStage
The only actor that results in a mix of the old Container API and the
new Actor API is ClutterStage. By inheritance, a Stage is a Group, but
we don't want it to behave like a Group - as it already overrides most
of the Actor API, and the reason why it was made as a Group in the
first place was convenience for adding/removing children.

Given that touching Group to make it aware of the new Actor API has
rapidly devolved into a struggle between a Demiurge that tries to
avoid breakage and a Chaos that finds new and interesting ways to
break ClutterGroup, let's declare API bankruptcy here and now.

ClutterStage should override ClutterContainer methods, and use the
layout management of ClutterFixedLayout as the proper class that it
was meant to be ages ago. Let ClutterGroup rot in pieces.
