+#X text 28 244 saving a (matrix) state can be accomplished by the 3dp_push
+object. the default matrix is the modelview matrix. it works as follows:
+both the right and the left outlet propagate the same matrix state
+as the input. so in short you can use 3dp_push to split your rendering
+tree into parallel branches. the matrix types that can be pushed are:
+modelview \, texture \, color \, projection. setting a current matrix
+can be done using the 3dp_mode object. i.e. will map all geometric
+transforms to the texture matrix \, for texture coordinate animation.
+the left outlet restores the current matrix back to the modelview matrix.
