//xg has only one light color (a diffuse one)
//opengl lights have the following colors: diffuse, ambient and specular
//also opengl has a global ambient color independend of a individual light
//gx has 2 material colors: diffuse (mat) and ambient (can also be considered part of light?)
//opengl material have the followning colors: diffuse, ambient, specular and emission
//so we (may) have problem (or call it a challenge)
//now how does opengl calculate light with all these colors
//vertex color = material emission
// + global ambient scaled by material ambient
// + ambient, diffuse, specular contributions from light(s), properly attinuated
//
//let us take these apart.
//
//material emission is like a constant color. So we can just add this in a tev stage. The only problem is how to add a color to a specific stage?)
//
//global ambient scaled by material ambient
//this is global ambient * material ambient so we can feed that result to an tev stage.
//
//Now comes the hard part as each color is used in the light calulation. And we only have once color in gx.
//Maybe we are lucky as each colors term is added to each other and only then used in light calculation
//So we might get away with just adding the 3 colors upfront and feed that as color to the light source
//But first let see how these terms are calculated.
//
//Ambient Term = light ambient * material ambient = GXChanAmbColor ?
//Diffuse Term = surface * (light diffuse * material diffuse) light diffues = light color | material diffuse = GXChanMatColor (let gx handle this)
//Specular Term = normal.shininess * (light specular * material specular) (let gx handle this, but add lspec*mspec to GXChanMatColor)
//
//now we could use 3 light to emulate 1 opengl light but that would not be helpfull
//so maybe there is an other way also gx material misses color components
//
//gx has max to channels
//each can be setup differently so we can have on chanel for normal diffuse
//and the other for specular. But we only have on light color so unless the specular color equals light color this it not usefull)
//maybe some experiments with GXChanMatColor help with that? So light color to none and all color CHANMatColor?
//
//also we have multiple tev stages.
//as we have used 2 channels we have to use 3 stages
//stage 1 = emissive + global ambient scaled by material as constant color (maybe 2 stages?)
//stage 2 = ambient + diffuse
//stage 3 = specular
//
//So this might do the trick in theory. Now on to practice...
//<h0lyRS> did you try setting specular to channel GX_COLOR1A1, and diffuse to GX_COLOR0A0, so you can blend them anyway you want?
//this could add an extra color?
//one way is adding the specular light, other way is multiplying
