Merge branch 'immediate-removal' into GLSL-master

Conflicts:
	Source/Core/VideoCommon/Src/PixelShaderGen.cpp
	Source/Plugins/Plugin_VideoSoftware/Src/SWRenderer.cpp

immediate-removal is a new created branch seperated from master but reverted the revert of immediate-removal
so we get less conflicts by merging
