Improve dialog layout and fix UI policy issues with all of the dialog
boxes in the Gerbview and Pcbnew code paths.
Updated the use of component to footprint where appropriate.
- New GAL draw layers for GerbView
- Improved bounding boxes for Gerber shapes
- Switched to use of SHAPE_POLY_SET for polygons
- Add GAL methods to support selection and rendering
- Add GUI support of editing GAL options
- Rename get/setActiveLayer to Get/SetActiveLayer to match convention
This feature was not reliably available: neither pl_editor nor GAL supported
it. It has been replaced over the past few commits with a new zoom-to-selection
tool available in all applications and modes.
File "rules" has instructional text as comments near top.
2) Convert all text files in repo to LF line ending form.
Any checkout done with "rules" in play will convert the working
tree to native line ending, while keeping repo as LF line ending.
