p position
* if w is not specified it defaults to 1
n normal
t texture coordinates
c color
* if a is not specified it defaults to 1
v vertex
T tangent
P primitive
mtl material definition
* name can contain spaces if quoted (see quote(2))
* ambient, diffuse and specular parameters take colors in linear RGB space
* diffusemap assumes the image colors are gamma-corrected (sRGBTexture)
* specularmap and normals both assume image contents are linear (RAWTexture)
indices (ᵢ) are zero-based
