For the scrolling on one page to be as fluent as possible,
the entire bitmap of the current page is held in CHIP-RAM.
As the CHIP-RAM is unfortunately limited, a limitation of
usable resolutions occurs. Normal dimensioned pages can thus be
displayed at 180 DPI, if not much more CHIP-RAM is needed for
other applications. In my case then about 5 KB CHIP-RAM is left
(from the 512 KB).
The size of the ShowDVI<#450#><#450#> screen depends on the size of the
Workbench screen. If the Workbench has been started in the overscan
mode, then ShowDVI<#451#><#451#> uses that mode too. Is the Workbench screen
in noninterlaced-mode and should the ShowDVI<#452#><#452#> screen be opened
in the interlace-mode, then the y-resolution of the Workbench screen
is doubled.
