- Fixed a few font related problems.

- Fixed: ASkyViewpoint::Destroy was missing the super call.
- Added SnowKate709's A_LookEx update.
- Moved M_DrawPlayerBackdrop into DCanvas as a virtual function. Since this
  directly accesses the frame buffer it must be overridable for renderers
  that work differently.
