If the Complete event has this mode, the client is not using
the more optimal format/modifier for the buffer allocation. The
client must explicitely inform the server that it understands
this mode by adding the PresentOptionSuboptimal flag when calling
PresentPixmap.

Its main usage as of now is to allow clients to re-fetch DRI3
format modifiers as some modifiers might allow direct scanout.

Bump presentproto version to 1.2.
