rollup-plugin-glsl-minify

A rollup plugin to minify glsl on the fly.

Known issues to avoid

* property confliction
albedo conflicts with materialUniforms.albedo
``glsl
vec4 albedo = vec4(1.0);
materialUniforms.albedo *= albedo.rgb;
`

* variable name in vec4
`glsl
uniform vec2 texSize;

void main() {
vec2 invSize = 1.0 / texSize;
//vec4(invSize, invSize); will be transformed to vec4(a)
vec2 uvOffset = vec4(1.0, 0.0, 0.0, 1.0) * vec4(invSize, invSize);
gl_FragColor = uvOffset;
}
``

* built-in name conflicts (内置函数名不能用于变量名)
* distance

* 变量名不能太简单，例如单字母，会与混淆生成的变量名冲突
