When texel samples are not exactly on texel centers, weight calculations
will involve a divide by a number very close to zero, resulting in
precision issues. Restore normalization of weights to compensate.
'obs_properties_apply_settings' and 'obs_properties_remove_by_name'
would incorrectly ignore property groups and not call the callbacks
or remove the property, resulting in quite glitchy UI.
This fix works by splitting the internal logic of ...apply_settings
into an extra function to call, while keeping the API the same. The
change to ...remove_by_name is to simply recursively going into the
group content with the same function call.

The shaders to unpack YUV information from the same texture were rather
complicated. Breaking them up into separate textures makes the shaders
much simpler, and we can remove the PRECISION_OFFSET hack.
Performance also gets a nice boost on Intel for planar textures.

Allows the ability for users to add custom browser widget docks that
they can use for their third party services if they feel the need,
mostly as a convenience tool so they don't have to open extra browsers
alongside the program.
These functions allow item delegates (editors) or item widgets with
event filters to detect whether a user has finished editing a line edit
control. This separates the code so it can be used elsewhere than just
in the source tree widget.
The video format is not updated if switching between cache-compatible
formats, e.g. YUY2 and YVYU, resulting in the wrong conversion technique
being used. This change ensures the format is always up-to-date.
