Fonts may not yet line up properly, especially in room_sim_3d where fontsize
is used to show z position. Also, no effort was made to improve the interface
of these classes. For example, size changes don't bump the source values
back within the bounds of the object.

ALSA MIDI backend: Quick and dirty fix for bogus zero-velocity note-off messages; output a note-on with zero velocity instead.

Added a "floatsize" method to [pdinfo]
Cleaned up the format specifier for [print] and gui_vmess
Got rid of unnecessary "l" in "%lg"

canvas_events

This makes it easier to point the gui dir at a local copy of the repo for
easier development. You can use this to make it easier to test out changes
to the GUI in purr-data/pd/nw.

Setting GUIDIR should even work if you haven't installed Purr Data to the
system. Just make sure the nw.js binary has been downloaded and expanded to
purr-data/pd/nw/nw. (This happens automatically when you build.)
