Initial Commit
GUI layout and coding beginning
image input and output filters created and tested in code. next phase will be to create GUI elements with drag/drop for them, and output preview panes.
starting GUI work. stepping from iOS to OSX is a bit confusing..
default graph views now have tracking areas set up for moving. connections to do next
scroll view and corresponding document view are now subclassed for autosizing and for the connection drawing layer (document view draws connection arrows between nodes, which are in turn connected as subviews and do their own drawing/will provide their own connection points).
added ability to log stuff easily to GUI
image output nodes now have delegated output view
factory class for creation of filter nodes, graph views, and output panes. using frame style to indicate which output pane is which, but that's deprecated, so will look for a better way eventually
pull update implemented (ie just call once on output node. moved some files around
first effects node created and tested. works. haven't done anything with configurable values yet though, that's next
