Isn't the description in the docs enough?

Fully load all shaders to prevent future performance hiccups.

Usually graphics drivers do not actually prepare shaders until they are first needed. However when some object is first rendered with a previously unused shader, there can be a hiccup because the driver is compiling/optimizing the shader. This can be quite noticeable on mobile platforms.

Calling this function will perform dummy one-invisible-triangle rendering with all permutations of all currently loaded shaders. This can take some time but helps to avoid hiccups in the future.
