Base glTF only allows jpeg and png images. obj2gltf should try to convert other common image formats like targa and bmp to png before writing out the glTF.

And also obj models with no image texture, and having RGB vertex coloring. Models like v X Y Z R G B v 2000 1500 250 0.25 0.36 0.75 ...... ..... To confrim?
