It's pretty much pointless to have two API references:
• the Cally API reference is fairly small
• the build system is already complicated as it is
• GTK-Doc isn't smart enough to ignore sub-directories
• Cally is not a separate library, just a separate namespace
There are some issues with GTK-Doc not accepting multiple namespaces,
but nothing seriously tragic.
Commit 79849ef1d5fff9acd310cd68d59df0c7cf2cb28f had a typo in the
device property format check. This property is formated in 8-bit
items, not 32-bit.
This went unnoticed till now because some touchpads were still being
detected as such due to a second check below:
else if (strstr (name, "touchpad") != NULL)
source = CLUTTER_TOUCHPAD_DEVICE;

It could happen that gdk_screen_get_setting fails to retreive
Gdk/WindowScalingFactor which leads to the following warnings when
clutter_init is called:
GLib-GObject-WARNING **: value "0" of type 'gint' is invalid or out of range for property 'window-scaling-factor' of type 'gint'
GLib-GObject-WARNING **: value "0" of type 'gint' is invalid or out of range for property 'dnd-drag-threshold' of type 'gint'

Slightly edited to fix up whitespace issues.

The paint opacity for a top level is always overridden to be the full
value, since it's a composited value and we want to paint our scene.
When clearing the stage framebuffer, though, we want to use the actual
opacity, if ClutterStage:use-alpha is set.
-1 is explicitly an invalid value to pass to eglSwapBuffersWithDamage,
and the specification admits as much:
If
eglSwapBuffersWithDamageEXT is called and <n_rects>, is less
than zero or <n_rects> is greater than zero but <rects> is
NULL, EGL_BAD_PARAMETER is generated.
Fix up our usage of SwapBuffersWithDamage to match the behavior in the
EGL specification.

These are just terrible API that we've been stringing along since the
0.x days. We cannot truly deprecate them, because they are, in some
cases, the only actual API to perform some operation, and porting all
the code in the world is not going to make us any friends.
For the time being, we use a deprecation notice in the documentation.
The macros are useless for language bindings, and are terribly unsafe
from C as well. There's always the option of using the GObject
properties they refer to, but it's more efficient to just have a simple
getter function.
While each stage has at most a GdkFrameClock, the same GdkFrameClock
instance may drive multiple stages per frame. This means that the
mapping between a GdkFrameClock and a ClutterStage is a 1:M one, not a
1:1.
We should store a list of stages associated to each frame clock
instance, so that we can iterate over it when we need to update the
stages.
This commit fixes redraws of applications using multiple stages,
especially when using clutter-gtk.
_cally_actor_get_top_level_origin() uses a compile time check
without runtime check, which will obviously fail when another
backend like wayland is used.

When multiple relative motion events are received and queued, we can't
base the relative => absolute motion conversion off of the stage pointer
position, since that is only updated when the queue is processed at
the beginning of each frame. The effect of trying to use the stage
pointer position was that subsequent motion events were effectively
dropped.
To improve things, switch to keeping track of the pointer position
ourselves in the evdev backend and adding to that.
This has the side effect of making the internal function
_clutter_input_device_set_coords not effect the internal coordinate
state of the evdev stage, but AFAICS there is nothing depending on that
so that should be fine.

There's no point in trying to go ahead if we don't have a context to
create the CoglOnscreen framebuffer, and Cogl will crash anyway if we
pass NULL to the constructor.
With server-side buffer allocation, buffers may be returned out of order
(e.g. they may be held onto by external references or hardware). As such
we may see older buffers the frame after we discard the history from
seeing a very young buffer. To overcome this we want to keep the history
in a ring so we can keep track of older entries without keeping an
unbounded list. After converting to a ring, the maximum buffer age
observed during testing was 5 (expected value of 4), but before we could
see ages as high as 9 due to the huge latency spikes caused by doing full
buffer redraws (compounded by external listeners doing readback on the
damaged areas, for example vnc, drm/udl, prime). For this reason, a
maximum age of 16 was chosen to be suitably large enough to prevent these
worst cases from taxing the system.
v2: Fix off-by-one in combining the damage histroy into the clipping
rectangle, and apply copious whitespace fixes.
