Hi,

virtio-gpu has optional opengl support, and ideally the default behavior
is 'enable opengl support in case the UI supports it'.

For SDL I'd like to have it initially disabled by default, then later
when it proved to be stable flip the default to enabled.

Hmm, that could work. Have some ${ui}_early_init(), called when
parameters are parsed, to figure whenever opengl is available (and
possibly have different opengl-enable defaults per UI) but don't do full
initialization yet.
cheers,
