Fixes

• Fixed error handling within compressor so that it doesn't crash if certain errors are received.
• Fixed bug where keyboard compositor would sometimes draw itself into the first frame of the movie even when no keys were pressed.
• Fixed crash while stopping recording.
• Fixed bug that could cause a crash when changing watermarks, camera or other compositors.
• Fixed bug causing texture leaks in the capture pipeline.
• Fixed a number of audio bugs (causing crashes). The system will now warn you if it can't do something (like set the default output device back to what it was before).

• About box, menus and window title now show 'iShowU HD Pro' if you are using the Pro version.
• Increased the height of the key press overlay.
• Control characters (sp / esc) removed from the key press overlay.
• Capture rate now limited to the refresh rate of the display (smoothes things out if you're running a low refresh rate).
