Detailed Description

  • takes wx events,
  • fixes all wx quirks (mouse warping, panning, ordering problems, etc)
  • translates coordinates to world space
  • low-level input conditioning (drag/click threshold), updating mouse position during view auto-scroll/pan.
  • issues TOOL_EVENTS to the tool manager
