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.
