For some reason, the combination of QPlainTextEdit and a HTML block
seems to treat spaces as HTML shoult (only display one, no tabs, etc)
rather than how QTextEdit + HTML does, which is strange. As we don't
need HTML for existing log lines, insert them as plaintext, but for
new entries wrap non-error non-warning messages in a <font> tag and
format that with white-space: pre
Replace fixed Arial, 7 px meter scale font with the font used
for VolumeMeter/QWidget. Add qproperties for meter bar thickness and
a scaling factor for the meter scale numbers. If not specified in a
QSS, defaults are 3 pixel bar width and 80% of base font size.
Sort video device entries with `alphasort` on non-Linux platforms,
as opposed to `versionsort` on Linux.
(`versionsort` is a GNU extension, unavailable on e.g. FreeBSD.)
UI: Fix call to `to_string` on FreeBSD
This commit includes two big changes, alongside other smaller tweaks.
1) Update the internal QTextDocument of the text component directly
2) Use QPlainTextEdit, which supports HTML & is designed for long text
3) Use QString's arg function for formatting strings
Fix 1 significantly improves realtime performance when adding lines
individually, to the point that the UI no longer freezes if the viewer
is open and the log is being spammed. It also improves initial launch
speed when there's a large amount of text already in the file.

Fix 2 completely eliminates delay when opening the viewer, regardless
of how many lines are already in the log file. For a standard log
after OBS launch, this cuts opening time from about 2 seconds to half a
second. For anything longer than 1,000 lines, the UI no longer freezes,
and the viewer (& its contents) open within half a second.

Use weak references on OBS objects that properties view reference in
order to ensure that the objects are still valid.
This fixes a crash where properties views would use objects without
necessarily knowing whether they were still valid or not.

Removing the first call to `video_output_stop` prevents the `data_mutex`
field in `struct video_output` from being destroyed while still in use.
The `render_preview_source` function will call `video_output_lock_frame`
upon that mutex and encounter a NULL pointer exception.
For some reason, SetWindowDisplayAffinity can make windows visible even
when it sets the same value for affinity that GetWindowDisplayAffinity
reports. Possibly an API bug as this is probably not a widely used API
yet?
Fixes a weird window with no size appearing when browsing for files on
Windows.
OBS_PROPERTY_GROUP creates neither a widget nor a label, causing
AddProperty to create a default one. Without a widget, it does not
get attached to the layout, resulting in a memory leak.
This commit also simplifies a bit of the code to avoid repeatedly
testing the same condition.
They detection for this was not checking the n selected items but the
first n items in the list, which would lead to the options being enabled
or disabled based on the whether other items were locked.
This uses the SetWindowDisplayAffinity API to hide windows from capture
applications (including OBS). This is not perfect - internal windows
such as context menus, combo box dropdowns, etc will still be displayed.
Even with these limitations, it should help people with single monitors
capture content with less interference from the OBS window.
This implementation is for Windows only but the code is generic enough
that adding other platforms should be straightforward.
