freeze window size persistence until maximized detection is available

Saving w.Canvas().Size() when the window is maximized persists the maximized
dimensions, corrupting the stored size for the next launch. Commented out the
save calls until per-OS maximized detection (IsZoomed / _NET_WM_STATE /
NSWindow.isZoomed) is implemented. Roadmap entry updated to reflect frozen
status.
