Beta 4: (possibly final)

• Added new level between pre and post shaders (0 in GUI, selected by default) which works exactly like pre-2.6.0 versions. Some shaders (hq2x for example) requires input texture in original Amiga display resolution and output texture in final output resolution or result will be quite crappy. D3D h2x really works again.
  
• Some on the fly graphics config settings (uae-configuration) reset RTG state.
  
• RTG screen mode selection in Display panel wasn´t active if Z2 RTG was enabled.
  
• AROS ROM updated.
