Currently SrcBlendAlpha and DestBlendAlpha are both ONE, and can
combine together to form two. This is not a noticeable problem for
UNORM targets because the channels are clamped, but it will likely
become a problem if FLOAT targets are more widely used.
This change switches DestBlendAlpha to INVSRCALPHA, and starts
backgrounds as opaque black instead of transparent black. The blending
behavior of stacked transparents is preserved without overflowing the
alpha channel.
Previously enabling and disabling bandwidth testing in a certain order
lead to the parameter being included in the stream key that is saved to
disk, making it impossible to disable the bandwidth test later on.
By doing this properly and using string concatenation instead of
modifying (appending to) the key_ value this will no longer happen.
It appears there's a projection flip that is applied in some situations,
like the preview pane in studio mode, and the shader math fails when
it's active causing the output color to be zero. This fixes the math for
GLSL (with a tiny redundancy penalty to HLSL), and cleans up some
unnecessary code along the way.
Use abs() to avoid zero area in case the OpenGL projection flip is
active. Also simplify the math, and remove the unnecessary sampler
state.
All UI elements are accessible through the obs frontend api via
obs_frontend_api_get_main_window, except for the tray icon and its
elements. This commit adds an obs_frontend_api_get_system_tray function
which returns the pointer to the QSystemTrayIcon cast to void (much like
the QMainWindow pointer for the main window).
This solves the issue of users who close the primary dock widgets and
can't figure out how to get them back, who for whatever reason choose
not to read the message box when closing dock widgets that tells them
how to get it back. The users can still hide the primary dock widgets
via the View menu, but they can no longer close them via the [x] button
on the dock widget. This change does not apply to secondary dock
widgets, such as a chat window, stats, etc.

While performing a release candidate, it is important to use an actual
version before the actual release candidate version so that the
auto-updater will know to update to 23.1.0
Fixes a crash that can happen if you try to use the settings window
while in an even subloop, or if you try to close OBS while in an event
subloop. Continually retries (defers) the actions every one second
until the subloop has finished.
The quadro P5000 would incorrectly be considered blacklisted because it
used a string search for the P500, which is an earlier quadro variant
that does not have NVENC support.
To fix this, instead of just doing a string search, additionally check
to make sure that there preceding or trailing numbers on the adapter
name.
OBS_EFFECT_AREA from 7d811499e was inserted in the middle of the enum,
which breaks ABI for any binaries that use
OBS_EFFECT_PREMULTIPLIED_ALPHA or OBS_EFFECT_BILINEAR_LOWRES.
