amii_outrip relies on LoadRGB4/transpalette fade and raw BltBitMap
to a SMART_REFRESH window -- chipset-era idioms that do not reach
the visible display on Picasso96 or CyberGraphX screens. On RTG
the screen stayed black and the user saw nothing between the
death messages and the high-score list. Detect RTG by screen
size > 800x600 and fall through to genl_outrip so RTG users get
the ASCII tombstone instead.
Switch the still-graphical path to BltBitMapRastPort so the blit
goes through the layer system, and move CloseWindow(ripwin)
outside the Forbid()/Permit() pair (same fix as amii_cleanup).
Rename cmap_white/cmap_black to cmap_outline/cmap_fill -- those
variables actually hold the indices of the darkest and lightest
palette entries, used for the four offset outline strokes and
the centered fill stroke respectively; the old names were
backwards.
