/*
You return LXfTMOD_DRAW_PIXEL from your ToolModel::Flags method.
Then you'll be called for drawing into screen space.
If you support multiple drawing modes; 3D and screen space,
you can test in your Draw callback by calling ILxView::Flags,
and testing the return type for LXiVIEWv_PIXEL.
You can query the StrokeDraw object passed to your draw method for an ILxView.
When you're in your drawing call, you can call ILxView::Dimensions to get the size of the viewport
to calculate the position to draw.

// This is not entirely working as it crashes MODO when an item with this drawing
// is selected and transform tool is enable. So something somewhere has to return bad value at some point
// and this sample is not handling that.
// This code needs to be executed from within item's Draw method.
// Drawing is aborted if mouse pointer is more then 120 pixels from the item to be drawn.
// The idea is to only draw the item when mouse pointer is close enough to it.
