Prunes code used to workaround libobs "user sources" (such as
sourceSceneRefs) and instead simply holds its own references and saves
sources it chooses with obs_save_sources_filtered.
Currently creating new sources can cause a deadlock:
OBSBasicSourceSelect locks the scene mutex when adding a new source
(required to add invisible sources), and later OBSBasic tries to
lock the graphics mutex (via CreatePropertiesWindow); meanwhile the
graphics thread is holding the graphics mutex and tries to lock each
scene as it renders them, resulting in a (non-obvious from the code)
lock ordering conflict.
Moving the CreatePropertiesWindow call out of the locked scene mutex
restores the previous lock ordering; in addition, the requirement
for keeping sourceSceneRefs for opening that initial properties
window is removed
Note: This functionality should probably be considered as a temporary
solution. Ideally, sources should not be visible on creation until the
user presses "OK" in the initial properties dialog. Also, the problem
of initial visibility can additionally be solved by implementing the
preview/program functionality. Once preview/program is implemented the
need for this patch will be negated, and the option should probably be
removed.

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
Typedef pointers are unsafe. If you do:
typedef struct bla *bla_t;
then you cannot use it as a constant, such as: const bla_t, because
that constant will be to the pointer itself rather than to the
underlying data. I admit this was a fundamental mistake that must
be corrected.
All typedefs that were pointer types will now have their pointers
removed from the type itself, and the pointers will be used when they
are actually used as variables/parameters/returns instead.
This does not break ABI though, which is pretty nice.
Changed:
- obs_source_gettype
To:
- enum obs_source_type obs_source_get_type(obs_source_t source);
- const char *obs_source_get_id(obs_source_t source);
This function was inconsistent for a number of reasons. First, it
returns both the ID and the type of source (input/transition/filter),
which is inconsistent with the name of "get type". Secondly, the
'squishy' naming convention which has just turned out to be bad
practice and causes inconsistencies. So it's now replaced with two
functions that just return the type and the ID.
The naming here is a poor choice, a source type determines if a source
is either a regular input, a filter, or a transition. The ID is the
actual unique identifier of a source.
The locale parameter was a mistake, because it puts extra needless
burden upon the module developer to have to handle this variable for
each and every single callback function. The parameter is being removed
in favor of a single centralized module callback function that
specifically updates locale information for a module only when needed.
When creating a source, it was possible to create duplicates. That has
now been fixed. I think that perhaps libobs shouldn't even allow for
duplicates in its core code, just to be safe. Will have to consider
doing that in the future.
Add a 'source selection' dialog to replace the 'enter a name' dialog.
This new dialog allows you to make new instances of pre-existing sources
so that you can add a pre-existing source to a different scene, or in to
the same scene more than once.
Also started implementing locale.
Comtemplating switching to JSON-based locale later, so we can add things
like descriptions/disambiguation, and so we can use jansson's built-in
hash table when doing the string lookup.
