* More formats recognition for "Clear Screen" step. Improved the ability handling the alpha channel (% color translucency). * Related to CPUID detecting: - Added support displaying correct SysInfo for recent multicore Intel CPUs x86-64 with HT/SMT (Core i3/i5/i7 and Xeon) based on Nehalem architecture. + minor and passive changes. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@6604 8ced0084-cf51-0410-be5f-012b33b47a6e
