- Removed the screenshot parameter from D_Display(), since it was a relic of

a long-abandoned experiment to write directly to video memory instead of
  to a temporary buffer in system meroy.
- Added Direct3D versions of the melt and burn screenwipes.
- Fixed the strip sizes for the melt screenwipe to match what Doom would have
  produced on a 320x200 screen, rather than producing more, thinner strips
  for wider screens.
