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.

In the Dark theme, disabled UI elements had text that was too close in
color to enabled UI elements. This commit switches them to use the
"light" palette color instead of the "lighter" palette color.
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.
Due to the recent change in which scene items now only update their
transforms during the next frame's tick, snapping sources would
sometimes jitter and have incorrect snapping. This fixes that issue by
reverting to the behavior of updating the transform immediately rather
than deferring the update to the next frame tick, but only on non-group
items.
This should not be done on items that are sub-items of groups because we
rely on the obs_scene_item::update_transform variable to update the
parent group's transform in addition.
Instead of updating the scene item texture any time
update_item_transform() is called, only update it when
obs_scene_item::update_transform is called. Prevents having to lock the
graphics mutex needlessly.
Adds the ability to set the current palette for the program via adding
"OBSTheme" objects to the qss files. The values for the OBSTheme object
are the values used by QPalette::ColorRole.
Modifying the global palette allows the ability to easily/quickly look
up application theme colors (especially if you would like to use them
for QML), as well as the ability to fix the hyperlink color issue. (On
dark themes, links would still be dark blue, causing them to be
difficult to see)
