Allows the user to snap sources to the edges of other sources, on by
default.

Closes jp9000/obs-studio#530

Allows users to snap sources to the horizontal or vertical centers of
the screen.  Off by default.

Closes jp9000/obs-studio#528

Allows the user to disable snapping all together or control the snap
threshold.

Determines whether an obs object was created successfully.  If a plugin
that's used for a saved object is removed (third party plugins), its
data will become invalid, but the objects can often still be created for
the sake of preserving user settings, but sometimes these objects can
cause problems if they're actually used (such as using them for
transitions).

Prevents issues from being able to update files that may not be using
the current system encoding on windows.

Windows needs filenames to be processed as wide, while libobs operates
on UTF-8, so a windows-specific function is needed here.

Useful for two purposes:

1.) When many devices are hooked up to the system and used in separate
scenes, but only one device active at once is desired

2.) Allows users who are dependent on outputting audio to desktop to
disable that audio (via disabling that device) when the device isn't
being displayed

This error implies to the user that the server still thinks they're
logged in, but that apparently no longer happens (at least on Twitch).
If the error happens, it usually means that the key is invalid or that
there's some general server issue, so update the message to reflect
that.

Fix redundant specifiers and change specifiers to match Linux date
command.

The crop texture would not always render correctly because the
projection matrix had not been set.

Renders the scene item to a texture if crop is enabled; otherwise
renders directly.

Allows the ability to defer updating the item transform until all
functions have been executed.

Allows the user to specify custom formatting for their recording file
names with many formatting options, viewed via tooltip.  The options
have been added to the advanced settings section.

Closes jp9000/obs-studio#507

Maps specifiers and accepts ones that work across multiple OSes.

On some systems, depending on locale, the specifier may resolve to an
empty string or nothing.  GenerateSpecifiedFilename will avoid
conversion of the specifier if this happens, to help guard against this.

Closes jp9000/obs-studio#526

Add support for devices that can output in grayscale (Y800).

(Note: Also modified the obs-ffmpeg plugin module)

Allows the ability for frame data to pass 8-bit grayscale images (Y800
color format).

Closes jp9000/obs-studio#515

Sometimes the timer will be triggered twice in one request.  GIF files
can be rendered in wrong speed.

Certain older devices (such as the Decklink Duo and Quad) could not be
selected due to the fact that they rely on BMDDeckLinkTopologicalID for
their unique identifier rather than BMDDeckLinkPersistentID.

text-freetype2: Use GS_A8 type glyphs texture

(Note: This commit also modified text-freetype2)

The implementation of get_modified_timestamp() did not check the return
value of stat(), so in case the check fails the values in the stats
structure can be any garbage on the stack and the value of
stats.st_mtime can change on every call. This can trigger a reload of
the image every second, even if the file was not actually modified.

Closes jp9000/obs-studio#520

Fixes the file integrity test when required files are placed in a path
containing non-english character encodings.

Closes jp9000/obs-studio#523
