X modified pde.properties slightly for console and header
X need stdout in p5 window b/c mac has no stdout X remove class 'PdeEditorOutput' and 'PdeEditorLabel'(?) X added editor.console.lines to pde.properties X int() and float() now work for casting X draw mode needs to be better for workshops X make size() work for draw() mode X inside Engine, reach in and grab calls to 'size' X if call is not using a constant number, then punt X when exporting, needs to grab this size parameter as well
