This commit adds a filter bar to the top of the hotkeys settings menu,
with it set to look for matches anywhere in the string label for that
hotkey.

Variables path and dir with the same declared size triggers a compiler
warning about possible truncation. Although, depending on the path
where profiles are stored, its still possible to go beyong the declared
size and the path will be invalid. This will not trigger any
compilation warning and all invalid paths will be cought by the already
check in the os_glob function.

OBS Studio currently does not support retina rendering for any of the
images in the app. This adds support for retina pixmap rendering as
well as adding higher resolution versions of each icon that was not
a high enough resolution to support 2x. The icons work when switching
themes and will only render the 2x versions when the device pixel
ratio is greater than or equal to 2.

I also added credits to the readme for images that were already being
used that require credit to the author. If the OBS community has
paid for these images already, I can remove the credits from the
readme. The credit is for the invisible, visible, and gear icons.

This creates a hidden QAction in sceneDocks and sourceDocks so we can
assign a shortcut to perform the renaming action.

It would only check whether it should download a package if the 32bit
version existed.  This would cause it to not download all files
correctly to update 64bit installs (post 22.0.1).

This reverts commit 2ce46965.

This reverts commit fba2ff8b.

Fixes a bug where removing quick transitions with no hotkey would
unintentionally remove the "start streaming" hotkey.  Hotkeys must be
initialized to OBS_INVALID_HOTKEY_ID (-1) instead of 0.  Hotkeys should
really be one-based rather than zero-based.

This was triggered by openning a fullscreen projector and trying to alt
tab. The projector was still on top but the first click on a KDE system
was returning a NULL activeWindow.

Normally on macOS, scrollbars are supposed to appear/disappear as you
scroll, but they would be on top of the content you're scrolling.
However, Qt has a bug where if you apply a custom theme to scroll bars,
they no longer disappear.  This causes things under the scrollbar (such
as the lock icons in the sources list) to disappear under the scrollbar,
because macOS normally expects those scrollbars to face out.  This fixes
that issue by adding a space to the end of the sources list box items to
allow space for the scrollbar.

Adds the same shortcuts in order to move filters around like sources

Delete key now should prompt to remove filters

Adds a new dock out of the stats widget.

In commit 57f8c5e3, a stretch spacer was put in to the filter window UI,
which was meant to be used when there's no video for the source.
However, it was always put in, and would stretch the layout even when
there was video.  This fixes that issue by only inserting a stretch
spacer when there's no video for the source.

When a user adds an item (either by adding or copying an item), select
it.  Fixes a bug with copying and pasting sources where the pasted
source will not have the copied transform applied to it.

Due to reports of issues with Windows 7, if the user is on windows
version 7 or below, set the default for "Browser Source Hardware
Acceleration" to false instead of true.  This ensures optimal user
experience and still allows those who had it working to continue using
it if they so choose.

Exact cause for this issue on Windows 7 is currently unknown.

In main menu, File > Show Recordings does not show the path for ffmpeg
custom output when it is selected in Settings.
This fixes the issue.

This is a weird one. On KDE just clicking in the options or right
clicking the empty space areas of the mixer dock would trigger a layout
change.

This fixes mantis #1256

Sub-items would incorrectly calculate as having bounds of {0,0} - {0,0}
because it did not enumerate group sub-items, so group sub-items would
not snap correctly.  This fixes group sub-item snapping so that bounds
of group sub-items are calculated, transformed by their group, and added
to the snapping boundary.  Bounds of group sub-items will now snap as
though they were normal items.

The ability to use multiple separate QSV encoders was added in Pull
Request #1341 (commit 3a08e858).
This error message was left in place, so let's remove it now.

Missed one string.
