John Beard d99fbddc22 Enable angle snap for pcbnew GAL ruler tool
This uses the two-point geometry manager to split the logic of the ruler
geometry and the preview item display. This allows the ruler to use that
manager's angle snap feature.

John Beard ce731f8b62 Add GAL microwave tools
This adds the microwave tools to GAL in Pcbnew as a new tool:
MICROWAVE_TOOL.

Some new preview items are introduced to support this:

* TWO_POINT_GEOM_MANAGER for managing construction of two-point
  geometries, such as that used to construct the inductor.
* CENTRELINE_RECT_ITEM a preview item to draw ractangle with a given
  aspect ratio along a line (specified using a TWO_POINT_GEOM_MANAGER)

PCB_TOOL gets a generic event loops which should be useful for more
than just microwave tools:

* doInteractiveItemPlacement() - handles event loops that wait for a
  click, create an item on click and then allow moving it
  around/flipping, etc.

John Beard 5f303f7b25 Enhance Pcbnew arc construction
This adds a richer overlay to the arc-by-three-points tool in Pcbnew,
including more guide-lines and a live display of radius and angle.

Also included is ability to go back to the previous step (if setting end
angle, you can go back to setting start point, etc) using Backspace, and
Ctrl snaps the start/end angles to 45 degree multiples.

This adds new classes

* MULTISTEP_GEOM_MANAGER: represents a generic "geometry manager" that
  builds up some geometrical construction based on a sequence of points.
  Used by:
* ARC_GEOM_MANAGER: handles the logical flow of constructing an
  arc by centre-point, set radius, set angle. This moves the logic out
  of the Pcbnew DRAWING_TOOL event loop in drawArc().
* ARC_ASSISTANT: graphical overlay to communicate current arc shape to
  the user during the drawing process

Jon Evans 082b8dd2a9 Refactor BRIGHT_BOX to common so it can be used by other programs 2017-03-11 21:38:01 +01:00
John Beard 8c3b8ee693 Add a ruler tool to pcbnew GAL
This allows to measure between features on a PCB. It uses a preview
EDA_ITEM in common, but due to the use of the IDs, it's currently
Pcbnew/Modedit only.

This also adds several "utils" for graphical functons useful when
drawing preview items on GAL canvases.

John Beard 9c08873210 Make SELECTION_AREA a generic overlay item
This simplifies the (already simple) SELECTION_AREA class. It is also
moved into KIGFX::PREVIEW and put in the common library, where it can be
reused by other GAL-aware tools (not just in Pcbnew) in future.

John Beard 5e84e953f3 Add a simple item class for graphical overlays
This introduces SIMPLE_OVERLAT_ITEM, which is an abstract EDA_ITEM,
designed for use as an overlay for assisting interactive tools.

The item is drawn only on the GP_OVERLAY layer, and sets the fill,
stroke and line properties before calling a virtual function to draw the
shape, which will depend on the implementaiton of the derived class.

The motivation here is to simplify and unify basic overlays used when
in interactive tools. It is not designed to be the base class of all
possible overlays - more complex ones would be more clearly represented
as their own derivative of EDA_ITEM.

Applications of this class can include: zoom/select rectangles, zone
polygon previews, geometric shape helpers, and so on.
