Removed code where if a PTS diff was greater than a certain
threshold it was forced to the previous PTS diff. This breaks
variable length frame media like GIF.
UI supplied per scene hotkey to allow switching between scenes; this
has to be done in the UI since it's up to the application to define
what exactly "changing/selecting a scene" means (changing the output
of channel 0 may not be enough for other applications)
OBSHotkeyEdit is similar to QKeySequenceEdit, except less terribad on OSX, while
OBSHotkeyWidget provides a container that automagically encapsulates multiple
bindings per hotkey
OBSHotkeyLabel in combination with OBSHotkeyWidget provides mechanisms for
dealing with hotkey pairs (see upcoming usage in window-basic-settings.cpp)
When a reconnect is occurring, the user doesn't really know that the
program is waiting to reconnect to the server or not, nor does the user
know how many seconds are remaining until that next attempt. This will
show the reconnect timeout countdown as it's occurring.
Implements exponential backoff for consecutive reconnects, which is
useful to prevent too many connections from trying to reconnect back to
a service at once over a short period of time in the case of potential
service downtime. Exponential backoff causes each subsequent reconnect
attempt to double its timeout duration.
This optionally allows the front-end to know what the current timeout
value in seconds is set to for the reconnection without having to call
an extra API function to find that out.
NoFocusFrameStyle was meant to disable focus frames around the scenes/sources
list (on OSX); unfortunately it also removed focus frames from controls that
should have focus frames like input boxes in the settings window
