vt is using static buffers for on screen data, the buffer size is
calculated based on maximum supported screen size and 8x16 font.
When using hi-res graphics and very smaller than 8x16 font, we
need to be careful not to overflow static buffers in vt.
Testing: I did test by building smaller buffers than vt currently is using,
royger was testing on actual 4k capable hardware.
MFC after: 1 week
Tested by: royger
