Encapsulates an extended modelview matrix stack.
OpenGL requires that implementations have a modelview matrix stack with a maximum depth of only 32. Regardless of that, the maximum depth can be expected to vary between implementations; and we don't want nesting of Transform nodes in VRML worlds to be constrained by this limit.
modelview_matrix_stack
uses the OpenGL modelview matrix stack until it fills up, at which point any additional matrices that spill over are pushed onto a conventional stack of mat4f
.
