Updated log defines to match SR upstream. Added new SR_CONFIG_PATHS for non Winddows and Linux systems. Not that SR works on them but to fix RA compile issues Updated SR2 code base to latest. Added supprt for windows monitor indexing. Fixed monitor index bug where index 1 was not being used corretly and "auto" was not being sent. Updated swithres for x86 windows fix fixed SR2 auto issue Fixed auto monitor bug Fixed monitor index corruption on Windows Fixxed buffer size bug Added correct fractal scalling. only used when required.
