[PD-dev] struct _canvasenvironment

[Miller Puckette]

It's in m_pd.h - that's a pretty good guarantee of stability (although
not 100% perfect I'm afraid.)

One caution -- if soneone 'saves' the patch into a new directory, the
canvas's directory will then change -- so it's best not to store the
result of canvas_settid() but to call it each time it gets used.

cheers
Miller
