Windows mirror driver versus WM hooks

[James Weatherall]

Matt,

The VNC Mirror Driver gets exact notifications of all rendering to the
screen, in the same way as any other video driver.  The VNC Hooks mechanism
monitors application's behaviour and uses a set of simple heuristics to
determine when to check for updates.  The performance of VNC Hooks can vary
depending on the types of application, the host OS, etc.

Cheers,
