Use bilinear filtering to reduce 36 taps to 25 for the regular path.
This works because the middle weights are always between 0 and 1,
allowing texture coordinates to be placed strategically to sample
correct ratios. I'm not sure about the undistort path, so I've left that
alone.
Also remove scaling added in #526, after which weight normalization is
unnecessary. If we want to use or invent an algorithm with alternate
downscaling properties, that's fine, but I don't think we should change
Lanczos scaling to mean something it's not. The scale implementation was
also seen not working when applied directly to scene items because of
assumptions made about the projection matrix.

(This also modifies the UI module)
Adds the ability for a source to monitor by default. This is mainly
aimed at browser sources, so that they do not stop outputting audio by
default like they used to.
When mixing sampling with raw loads in a shader, ending a shader with a
load would case the default sampler to become unset for OpenGL. Instead,
initialize with no sampler, and only set if there is a sampler.
The parameter "inFocus" was being given the opposite of what the name
implies: it was being set to false when in focus, and true when not in
focus. This fixes that confusion.
RGB to YUV converison was previously baked into every scale shader, but
this work has been moved to the YUV packing shaders. The scale shaders
now write RGBA instead. In the case where base and output resolutions
are identical, the render texture is forwarded directly to the YUV pack
step, skipping an entire fullscreen pass.

OBS has an option to warn before stopping a stream, but it doesn't have
a similar warning for recording. This can result in a recording being
unintentionally stopped.
Add an option to warn when the "Stop Recording" button is pressed.
Note: While OBS also has an option to warn on stream start, this
patch purposefully does not add similar warn on recording start option.
This is because accidentally starting to record isn't risky in the same
way that accidentally starting to stream is.
