Some vec4 functions from gl-matrix.
Will load all of the module's functionality and expose it on a single object. Note that any of the methods may also be required directly from their files.
For example, the following are equivalent:
var set = require('gl-vec4').set
var set = require('gl-vec4/set')Creates a new identity mat4
Set the components of a vec4 to the given values
Transforms the vec4 with a mat4.
