Function TextImageSize(X1,Y1,X2,Y2:Word):LongInt
Updates VX and VY : No
Updates Cursor Position : No
This returns the amount of memory required to hold a text image in
memory. Although a LongInt is returned, only a value up to
32 kb is permitted by VGA and SVGA cards at this time.
I think back to CGA (16 kb) cards and everyone thought 64 kb of
display memory was a lot and I feel I had better use a LongInt,
even though only 32 kb of text display is permitted.
