No renaming list is removing functions

[Pablo Martin]

The minimal case is:

precision highp float;

varying vec4 vColor;

void main() {
        gl_Position = vec4(0.0, 0.0, 0.0, 1.0);
}

using shader_minifier.exe -o output.glsl --format text --no-renaming-list "vColor" input.glsl

the result is:

precision highp float;varying vec4 vColor;

[Laurent Le Brun]

The behavior is indeed surprising.
For now, use --no-renaming-list vColor,main to keep main.

[Theron Tarigo]

The behavior shouldn't be changed as it is working as described, but this particular gotcha could be pointed out in documentation.

No renaming list is not removing functions, but rather:

• renamed unused functions are always removed by default
• no-renaming-list functions are not removed
• The default no-renaming-list is main (and mainImage, because of Shadertoy?)
