WINTERMUTE: Clean out some comments in the theora player
WINTERMUTE: Fill the screen with fillRect for now.
WINTERMUTE: Clear out some commented-out code.
WINTERMUTE: Make use of the wday-field in dates, instead of a wrong mday-value.
WINTERMUTE: Be case-insensitive when testing for sound-format.
PEGASUS: Optimize the nearest neighbor frame scaling a bit

Hopefully should improve performance on lower end systems
TONY: Removed some TODO warnings that aren't needed any longer
TONY: Replace _vm with g_vm.
TONY: Fix saveSoundSettings to use setInt for talkspeed.
TONY: Fix spelling of setStretch.
TONY: Removed some debug warnings which aren't needed any longer
TONY: Fixed problem with spoken voices being clipped when timed text mode is on.
TONY: Ignore draw attempts with non-positive width/height.

This avoids an invalid dirty rect (width -1) during the
introduction scene inside Halloween Park.
TONY: Fix background dirty rect handling.

Reset the scrolling state on load, so that when a new scene is
loaded, the background is redrawn. Also, revert the workaround
in d0d15af9, since this (hopefully) fixes the underlying problem.
TONY: Draw the dirty rectangle debugging last.

Otherwise the rects are overwritten by the actual drawing.
TONY: Use the right dirty rects for drawAA.

This makes it match the relevant non-AA code, and fixes problems
due to the invalid rects. (Perhaps we don't need dirty rects here
at all though, since all the callers seem to call the non-AA code
first with the same parameters?)
TONY: Mark screen dirty in RMGfxClearTask.

This fixes the "A LONG TIME AFTER..." screen when talking to the old
woman in the booth. Thanks to eriktorbjorn for noticing it.
TONY: Animate mouse cursors.

This restores the forgotten doFrame code for RMPointer, which fixes
the bird mouse cursor. Thanks to eriktorbjorn for noticing it.
TONY: Use Common::String in writeText.

This uses an array of lines rather than trying to stick nulls into
the string, and so fixes wrapping on hyphens (which overwrote the
character before the hyphen). Thanks to eriktorbjorn for both
finding the bug and working out what was going wrong.
TONY: Remove unused members of RMTextItemName.
