By putting matrices in a stack, a transformation can be expressed + COMMENT relative to another. You can {@linkplain #push push}, transform, render + COMMENT and {@linkplain #pop pop}, which allows you to restore the original + COMMENT state after rendering. + COMMENT + COMMENT
An entry of identity matrix is pushed when a stack is created. This
+ COMMENT means that a stack is {@linkplain #isEmpty empty} if and only if the
+ COMMENT stack contains exactly one entry.
