- Fixed: P_BounceWall() cannot assume that BlockingLine is the line the actor

- Fixed: P_BounceWall() cannot assume that BlockingLine is the line the actor
should bounce off of. Since the order lines in a blockmap cell are checked
for collision is essentially undefined, there could be another line closer to
the actor that it should bounce off of instead.
- Fixed: Thing_SetTranslation still used a 16-bit word to hold the translation.
- Bumped the maximum resolution up to 2560x1600.
- Fixed: DCanvas::DrawTexture() only expanded virtual screen sizes for widescreen
