diff --git a/u4_to_u5 b/u4_to_u5
 Oh hey, they updated the physics-engiOMG-EVERYTHING-IS-BROKEN!!1

 To match look of u4:
 - disable all light-baking
 - disable auto-patching shaders with fog (and switch fog back to whatever mode you were using)
 - set Light Bounce to 0 on all lights... or you'll get a warning!1 (on every spot-light)

 - Light-shaders are now overridden explicitly in the Lighting-tab
  ...all other shaders still override automagically... :p

 ShadowMap backface-culling now defaults to Back ("on" used to mean twosided). This can be "fixed" by setting it on a per-object basis FOR EVERY OBJECT IN YOUR GAME (you should create a script).

 Shaders
 - COLOR should now be SV_Target... POSITION should be SV_POSITION, unless it is a app2vert-struct...
 - the x2 factor on light-attenuation has been moved CPU-side, needs to be removed from all shaders.
 - unity_FogColor is now defined per default. Also, you should use the values in unity_FogParams.
 - object-scaling in unity4 is a source of many, many hours of horror:
  · if an object was uniformly scaled, the scale would be in the uniform unity_Scale.w, object-positions were untouched. The scale was part of matrices.
  · if an object was NON-uniformly scaled, the scale would be baked into vertices, matrices did not have scale
 - surface shaders have new ways to destroy you shaders in u5... this is a good opportunity to stop using surface shaders!
  · "alpha" now needs to be specified which type, defaults to the wrong one
  · alpha will be overwritten to 1.0 for opaqaue objects... add "keepalpha" to NOT destroy your alpha... ...
  · unity uses more interpolators, so fewer left for you. Rewrite surface-shaders to vert/frag... 
 - shadowmap sampling-functions have changed in subtle ways, on some platforms you now sample a depthmap.
 - you have probably always been calculating your worldspace-normals the wrong way... you should have been using the inverse-transposed _Object2World (which was not directly available)... in u5 you can use the utility-function UnityObjectToWorldNormal()
