1.7/1.8 scrolling with multiple passes

Void ProcessedShaderMaterial::_setTextureTransforms(const U32 pass)

Seems to contain quite a few refferences to U32 i, wich presumably at some point was intended to support multiple passes for different directions/speeds. This has been hardcoded to pass 0, with the resulting error being multi-layer materials breaking horribly on a second scroll pass(miscalculations when it functions at all). Unfortunately, at this point in time, haven't had the time to look into the ancillary functionality thats also been altered arround it to even offer up a quick-hack fix for this one.

reproduction step for this ones simple:

new Material(someMat001)
{
baseTex[0] = "texture1";
bumpTex[0] = "texture1b";
pixelSpecular[0] = true;
specular[0] = "0.3 0.3 0.3 1.0";
specularPower[0] = 12.0;
animFlags[0] = $scroll;
scrollDir[0] = "-1.0 0.0";
scrollSpeed[0] = 0.00125;
//=============== pass 2 ===========
baseTex[1] = "texture2";
bumpTex[1] = "texture2b";
animFlags[1] = $scroll;
scrollDir[1] = "-0.5 0.0";
glow[1] = true;
//pixelSpecular[1] = true;
//specularPower[1] = 8;
translucent[1] = true;
translucentBlendOp[1] = AddAlpha;
translucentZWrite[1] = true;
alphaRef[1] = 20;
};
