abe1cb1425 libobs: Support premultiplying images on load 
Add gs_image_alpha_mode enum for requested alpha handling: straight,
premultiplied with SRGB conversion, and just premultiplied. Both
premultiplied settings behave the same if the image is not SRGB, linear
is assumed.

Add gs_image_file3_t to store the alpha mode.

Add srgb.h file with helper functions.

Clean up vec4.h to use helpers, and remove unused functionality.

Update FFmpeg image loader to perform premultiplication on load.

ae7718a765 libobs, obs-filters: SRGB backwards compatibility 
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.

50dfa566e6 libobs: Filter using premultiplied alpha 
Convert incoming straight alpha color to premultiplied at filter begin,
and process premultiplied value at filter end.

If direct rendering is allowed, we assume the input source outputs
premultiiplied alpha. If not, that source will need to be updated.

This adds the drmbuf format as a parameter separate from the obs texture
format that will be used. drmbuf's may have a variety of formats that we
need to pass correctly to get a usable texture which may correspond to
multi-platform texture formats.
