This option can only be set per-sketch, and must be called before any use of textFont(). - * hint(DISABLE_DEPTH_TEST) - Disable the zbuffer, allowing you to draw on top of everything at will. When depth - * testing is disabled, items will be drawn to the screen sequentially, like a painting. This hint is most often - * used to draw in 3D, then draw in 2D on top of it (for instance, to draw GUI controls in 2D on top of a 3D - * interface).

Restore the default with - * hint(ENABLE_DEPTH_TEST), but note that with the depth buffer cleared, any 3D drawing that happens later in - * draw() will ignore existing shapes on the screen. - * hint(ENABLE_DEPTH_SORT) - Enable primitive z-sorting of triangles and lines in P3D and OPENGL. This can slow - * performance considerably, and the algorithm is not yet perfect. Restore the default with hint(DISABLE_DEPTH_SORT). - * hint(DISABLE_OPENGL_ERROR_REPORT) - Speeds up the OPENGL renderer setting by not checking for errors while - * running. Undo with hint(ENABLE_OPENGL_ERROR_REPORT). - * As of release 0149, unhint() has been removed in favor of adding additional ENABLE/DISABLE constants to reset - * the default behavior.
