    The set of shaders built in to LÖVR.  These can be passed to `Pass:setShader` or
    `lovr.graphics.newShader` instead of writing GLSL code.  The shaders can be further customized
    by using the `flags` option to change their behavior.  If the active shader is set to `nil`,
    LÖVR picks one of these shaders to use.
