Style: bool
I would prefer a agent_supports_graphics_device_info (or a comment).
But more than this I think it's on the wrong structure, it should be
in RedCharDeviceVDIPortPrivate where the state of the agent is stored.

The "adjust_agent_capabilities" is no more appropriate now, I would
change in "filter_agent_capabilities". Even better to have another
function to handle capabilities (see below).
OT: Note that VD_AGENT_SET_CAPABILITY above could overflow the message,
in this case not much of an issue, the buffer is statically allocated
in a structure and the change will stay in that buffer.

I think this change will cause the message to not be sent in case the agent connect
as the variable will be false at the beginning, when the capabilities are received
should be sent.
The variable should be reset also that the agent disconnect (reds_reset_vdp)
