Screen rotate video to mirror horizontally

[shredder]

I'd like haiku to mirror my screen horizontally, ie. rotate by 180 degrees the video output. I have a system where the video monitor mount is permanently fixed upside down due to space and cabling issues.

On other systems this was solved from software on an intel chipset. However as this is an older system and Haiku is generally terrific Haiku would be a better fit for the macinhe than other choices. However if the video cannot be reversed the users cannot use it. Apart from this being obvious, for example to report this bug, the human screen reading rate is maxing around 6.4 characters per second.
