[rescue] SPARCstation 5: framebuffer resolution wont change

I find this argument..unconvincing.

"Digital devices are made with analog components."

A flat-screen could do exactly the same thing, except feeding the video
signal to an A->D instead, at a clock rate PLL-synced to the input.
Phase is slightly more interesting, but still not all that difficult.

Not always.  The early ones were (almost?) all willing to letterbox
instead of scaling (and I prize the few I have that are); modern ones
less often, and scaling is sometimes done well and sometimes poorly.
(Indeed, what constitutes "well" and "poorly" depends at least in part
on the application.)
