Dm 4484 marker tool - create drawing layer for marker tool

[cwang2016]

The implementation includes:

• DrawObj for marker
• Marker dropdown list under the marker icon to show the marker and footprint items (will be added later).
• Marker drawing layer rendering and operation including action creator and action dispatch functions.
• Marker UI component shown in Drawing Layers popup.
  The implementation set up some work which can be similarly expanded to footprints in the future.

Maker drawing layer operation:

• select 'Add Marker' from dropdown list to add a new drawing layer
• click anywhere to locate the newly added marker
• click and drag the mouse to relocate or resize the marker:
  for relocation: click and drag inside the circle, then drag the mouse.
  for resize: click inside the circle, then click and drag the handler to resize
• label and its location are set from Marker tool UI

picky: marker not makler

UI Comments:

• Mostly it looks the like the old one and works better.
• On the Layer control: show: <title>, It the title should change as you enter text for the label. For example, Marker-1 would be how it started but when the user enters 'my favorite' it should change to that.
• The mouse should change to a pointer when you are on a marker. If you want to be really fancy it could change to a resize cursor on each resize box.
• The size is not in world coordinates, the position but the size is not. When I zoom the image, the circle size does not change with the zoom level.

more improvement,

• on the layer control, show: <title> and the title change as you enter the text for the label.
• the mouse changes to a pointer once the cursor moves onto the marker, and the mouse becomes a resize sign when the cursor moves on the handler of the marker.
• When the cursor becomes a pointer, the marker can be relocated by dragging the mouse, and when the cursor becomes a resize one, the marker can be resized by dragging the mouse.
• the marker size changes as the image is zoomed.
