Allows the ability to specify release candidate versions in the
whatsnew.json in order to allow startup information dialogs to be
displayed to the user which are specific to release candidates.
This commit adds the ability to select a background color for a
scene-item, whether it's a custom color or one of eight presets.
As this is an initial implementation, it lacks theme customizability,
and it also lacks the ability for the user to set their own preset
colors, so only the hard-coded 8 are available.
Contrary to what the name would have you believe, QPointer<> is not used
to delete a pointer when it leaves its specific scope. Instead, it's
used to check to see if the pointer is still valid. For most
QWidget-based objects, this is actually fine because QWidgets that are
assigned to layouts or other widgets will automatically be destroyed --
however, for non-widget objects, this can cause a memory leak.
This patch replaces QPointer with QScopedPointer where applicable to
prevent memory leaks.

Currently the only thing preventing a user from trying to start multiple
streams or recordings is the UI buttons being disabled. The hotkey code
allowed the user to bypass that, which for streaming resulted in lots of
rtmp output connect threads spawning, which stomped all over each
other's data structures and resulted in crashes.
This fixes a crash in case the user selected the option to save
projectors on exit and had multiple monitors at that time. Later on,
when obs is started again if the monitor list is lower now the open
projector code will return null when trying to create the saved
projector.
Just check if the returned projector pointer is valid before trying
to restore the saved geometry.
Because sub-items of groups can no longer reroute their signals to the
parent scenes of groups, delegates removal handling to SourceTreeItem
instead of OBSBasic.
Allows copying and pasting of groups. The user can fully duplicate the
group, or create a reference of the group. The user cannot paste a
reference of the group if it already exists within the same scene
however.
(This commit also modifies UI)
Changes groups to their own independent type, "group". This allows them
to be used like other regular types, and allows the ability to reference
groups in multiple scenes. Before, a group would always be linked to
the scene it was in. This made it cumbersome for users to modify groups
if they had a similar group in multiple scenes (they would have to
modify each group in each scene). Making groups like other source types
makes more sense to solve this issue so they can be referenced in
multiple scenes at once. This also removes a significant amount of
group-specific handling code required for implementing groups in the
front-end.
One limitation however: due to the way sub-items of groups are
seamlessly modifiable and sortable as part of the whole scene, the user
cannot have multiple references to the same group within one scene.
(This commit also modifies UI)
Removes obs_scene::group_sceneitem and replaces it with
obs_scene::is_group. Changes a number of other functions related to
groups so that a group is not inherently tied to a specific scene, and
helps allow a single group to be referenced in multiple scenes if
desired.
When the vertical volume meter was introduced it set in the OBSBasic.ui
mixer dock definition a min width/height that was valid for both
widgets. QStackedWidget hints the minimum size as the higher w/h
of its children so this workaround is necessary.
OBS_FRONTEND_EVENT_PREVIEW_SCENE_CHANGED is supposed to be called
whenever the user changes the current preview scene -- it was almost
never being triggered.
Makes it so the auto-updater does not have to rely on a cmake variable
being set. Fixes a bug where deployment could accidentally be built
without the auto-updater being enabled.
Instead of queuing AddScene to add the new scene to the list box,
ensures that the UI has added the new scene to the list box when the new
scene is added. This ensures synchronization between the calling thread
and the UI thread in this particular case.

Instead of manually having to call AddScene each time a scene needs to
be added, use the "source_create" global OBS signal to detect when a
scene has been created, and add the scene to the list automatically.
Allows the ability to add scenes to the main user interface via libobs
API.

Deferred load is used specifically for macOS systems to ensure that Qt
and CEF do not load at the same time. This causes a slight bit of a
delay in loading the scene after the UI has loaded. This is not
necessary for other operating systems, so revert to the older load code
in the case of different systems.
Add a new algorithm to calculate the true-peak. It implements the
Whittaker- Shannon interpolation from four samples to create 4
intermediate samples (5 x oversampling) inbetween the middle two
samples.
With 4 samples and 4 intermediate samples the algorithm can be
implemented as a 4x4 vector-matrix cross product, which is ideal for
SSE.
I've also replaced the sample-peak algorithm using SSE as well to
improve performance.

Audio controls in OBS Mixer and Advanced Audio Properties window are not
sorted at all. Every time OBS is restarted they get shuffled (Jim note:
This is due to json object hashing). The order of these controls is
additionally not consistent between the mixer and the advanced audio
properties window.
