Committing this separately from the rest to ease making a patch for just this
functionality in case that it might make it into the trunk.
This can function standalone, though it is less useful without the rest.
It requires that wxwidgets-3.0.0_macosx_magnify_event.patch be applied to wxWidgets
It is completely optional; everything is guarded by the USE_OSX_MAGNIFY_EVENT macro.
- Added OnMagnify event handler to EDA_DRAW_PANEL, EDA_3D_CANVAS and the helper for
EDA_DRAW_PANEL_GAL, WX_VIEW_CONTROLS. This should cover canvases all current tools.
- Guarded all with USE_OSX_MAGNIFY EVENT feature macro and added support in CMakeLists.txt
- SEGVIA becomes VIA
- Drill size moved from TRACK to VIA
- Removed shape from TRACK, becomes ViaType in VIA
- GetTrace becomes GetTrack, for uniformity
- Some minor constification and typo fixes
* All items shapes are converted to polygons.
* Polygons are merged layer by layer (for calculation time reasons,zones are not merged)
* for copper layers, vias and pads holes are substracted from polygons (but, for calculation time reasons, not inside zones areas).
* the look is better, mainly when displaying the copper thickness
* solder and paste layers are now shown in 3D viewer.
* the code was seriously cleaned (but still needs to be enhanced).
* Note this is a work in progress which needs refinements.
