please test for regressions and fixes. some little changes to make pixel shader more dx9 sm2.0 friendly. the condition is not to use pixel lighting ( sorry no hardware support for the quantity of parameters needed). git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@6777 8ced0084-cf51-0410-be5f-012b33b47a6e
