/// Compiling a material involves determining which Techniques are supported on the
/// card on which the engine is currently running, and for fixed-function Passes within those
/// Techniques, splitting the passes down where they contain more TextureUnitState
/// instances than the curren card has texture units.
/// <p/>
/// This process is automatically done when the Material is loaded, but may be
/// repeated if you make some procedural changes.
/// <p/>
/// This method should be safe for use on threads other than the main render thread.
/// </remarks>
/// <param name="autoManageTextureUnits">
/// If true, when a fixed function pass has too many TextureUnitState
/// entries than the card has texture units, the Pass in question will be split into
/// more than one Pass in order to emulate the Pass. If you set this to false and
/// this situation arises, an Exception will be thrown.
