Patch 04/10/16

• Only draw widescreen BG when necessary to limit Windows 10 rendering problems.
• Game starts with a larger screen area.
• Add button to cycle through perfect window sizes (Shift + F1).
• Add more pitch range to jump sounds.
• Prevent player leaving room directly after entering it, to prevent common issue where players would exit when trying to throwing item.

Thanks to notgreat for these suggestions.
