Well, now the name is similar to VOCTRL_QUERY_FORMAT but the behaviour
is completely different! In addition it provides a much more limited
functionality, e.g. vo_gl will be able to trivially support RGB and BGR,
possibly even YUV for OSD, but with this design it can only report one
supported format!
This design also makes it very hard to add support e.g. to indicate
which OSD formats are fast and which are slow for a given vo (currently
there is no need for this though).
The most flexible system is like for the VOCTRL_QUERY_FORMAT: for the
given image format, return what functionality the VO can provide.
Currently probably only VFCAP_CSP_SUPPORTED and maybe VFCAP_ACCEPT_STRIDE make
sense for the OSD.
