Glimmr Canvas Animation
version 1/111030 by Erik Temple
Section: A note on compatibility
Glimmr Canvas Animation uses a rudimentary system of "virtual timers" to enable animations to run at different speeds despite the fact that Glulx has only a single timer. This means that GCA is probably incompatible with any other real-time extension, at least if we are hoping to track real-time and animation events at the same time.
