Support Colored (Non-Standard) STL Files

[X-DE1]

I loaded this model with color and it appears without color.

I opened it at https://www.viewstl.com/ and it comes out with color.

Can you post the model as well?

Looks like color is not standardized for the STL file format, so I'm not sure if it makes sense to add that ability to fstl.

Here is the model.

Hm, extracting the color is not hard, it would "just" require another menu option as the both possible formats are BGR vs. RGB. I'm not familiar with the shader code, but I guess

fstl/gl/mesh.frag

Line 19 in 6221341

gl_FragColor = vec4((a*base2 + (1-a)*base00)*0.5 +

would be the place to change. I don't understand the maths yet, though.

I also need this feature and vote for it to be implemented.
