I am using libgrx2.0 and need to direct video memory access of all video
memory
on a hp vectra vl series 4 p/120 with s3 trio 64v+ chipset
functions needed include
1 write block of data to the screen quickly, typically this would be a row
or column of pixels.
2 scroll screen up/down , left/right to achieve waterfall display effect.

time for these operations is critical as this is a high speed real time
data logging/display application
any suggestions ?
Paul
