In order to do linear-correct filtering cheaply when scale filtering is
disabled, we need to know whether or not texture coordinates will always
sample from texel centers. This can be computed at the scene item level
relatively easily, and passed along to sources when rendering. Scene
items will use obs_source_set_texcoords_centered to set hint status, and
sources will use obs_source_get_texcoords_centered to retrieve it.
There is currently no way to enumerate *all* sources in OBS. Only
inputs and scenes have a way to be enumerated. Some applications
like obs-websocket have features that need to take advantage
of enumerating all sources in order to function properly.
Add OBS_SOURCE_SRGB to indicate sources that support SRGB rendering. We
can use this flag to know which sources do not know how to handle SRGB,
and disable accordingly inside obs_source_main_render().
We can also use this flag to clean up the filter interface and remove
the SRGB-specific functions. We also need to disable direct rendering if
the filter source wants to render SRGB, but the parent source does not
support it.
Scenes and groups are marked as having SRGB support, and those are
internal sources that we control.
Allows the ability to reset (erase) a source's existing settings and
replace them with new settings. This is useful for things such as
reverting to older settings.
Implements the Undo/Redo for scenes and sources, ranging from renaming,
deletion, addition. It also adds several elements to libobs that were
designed to facilitate undo/redo, and should not affect the rest of
libobs.

Changes the maximum resolution size to a resolution list, and splits the
maximum FPS to its own function.
(Note: ABI has not been modified because the last changes still haven't
been released yet, so it's safe to modify this as long as the changes
haven't been officially released)
(This commit also modifies rtmp-services)
Implements obs_service_get_max_bitrate, which allows retrieving the
maximum audio/video bitrates directly rather than being forced to use
the apply method. Makes it a bit easier to get the bitrate values.
This obs_service_t object callback was implemented specifically for
services which may have a maximum recommended width, height, and
framerate that needs to be enforced.
Useful for sharing translated text from modules with the frontend. This
is technically already done via properties, but it would be nice to just
be able to explicitly look up locale text directly rather than have to
go through properties.
Similar to how outputs can pass errors, add the same functionality for
encoders so that if an output encoder has an error, it is made available
to the output and eventually the UI / user.
(This also modifies image-source, obs-text, text-freetype2, and UI)
This improves source definition versioning. To do this, it now stores
two identifier names. One "unversioned" which is the original name, and
one "versioned" with the version number appended.
This fixes both backward compatibility with older OBS versions, and
fixes the inability to use "add existing" in OBS itself on sources
created from older version definitions.
Returns whether rescaling is enabled for an encoder. This will be used
with texture-based encoders to determine whether to fall back to
RAM-based encoding instead.
Adds API:
obs_scene_add_group2
obs_scene_insert_group2
obs_sceneitem_group_ungroup2
These functions should be used by plugins if they need to use these
functions and need to send a refresh signal. If a major API rework ever
happens the old functions should be removed. The old functions should
eventually be deprecated.
The reason why specifying a 'signal' parameter is useful is because it's
a bit more seamless for the user interface to be able to have custom
handling of these specific cases. It looks better and doesn't require
completely erasing/recreating the entire list, which is visually
unappealing.
Allows the ability for manual transitioning to smoothly flow
(interpolate) to the intended transition point over a short period of
time rather than simply setting a hard transition point number. Doing
this allows manual transitioning to occur more smoothly, and in a more
visually pleasant way.
Allows the ability to manually specify the transitioning point so the
user can transition at a custom rate, usually done by a device that can
be used as a T-bar

Adds functions to allow sources to inform the UI whether the audio is
currently active or not. Allows the ability to turn on/off the items in
the mixer.
