// Description:
//    Kailh Choc PG1350 (v1) + Kailh Choc PG1353 (v2) reversible and hotswappable footprint.
//    This includes support for LOFREE low profile POM switches (Ghost, Phantom, Wizard)
//
//    With the set defaults it will include support for choc v1 and v2 hotswap, single side
//    (Back).
//
// Nets:
//    from: corresponds to pin 1
//    to: corresponds to pin 2
//
// Params:
//    side: default is B for Back
//      the side on which to place the single-side footprint and designator, either F or B
//    reversible: default is false
//      if true, the footprint will be placed on both sides so that the PCB can be
//      reversible
//    hotswap: default is true
//      if true, will include holes and pads for Kailh choc hotswap sockets
//    solder: default is false
//      if true, will include holes to solder switches (works with hotswap too)
//    hotswap_pads_same_side: false
//      if true, and if not using plated holes, it will position the pads so that nets are on
//      the same side to simplify routing.
//    include_traces_vias: default is true
//      if true it will include traces and vias when hotswap is true, footprint is reversible
//      and when no plated holes are used, to simplify routing. In the other cases it's simply
//      not needed.
//    trace_width: default is 0.200mm
//      allows to override the trace width that connects the pads. Not recommended
//      to go below 0.15mm (JLCPC min is 0.127mm), or above 0.200mm to avoid DRC errors.
//    via_size: default is 0.6
//      allows to define the size of the via. Not recommended below 0.56 (JLCPCB minimum),
//      or above 0.8 (KiCad default), to avoid overlap or DRC errors
//    via_drill: default is 0.3
//      allows to define the size of the drill. Not recommended below 0.3 (JLCPCB minimum),
//      or above 0.4 (KiCad default), to avoid overlap or DRC errors 
//    locked_traces_vias: false
//      sets the traces and vias as locked in KiCad. Locked objects may not be manipulated
//      or moved, and cannot be selected unless the Locked Items option is enabled in the
//      Selection Filter panel in KiCad. Useful for a faster workflow. If using autorouting
//      solutins like Freerouting, locking can prevent the traces and vias from being
//      replaced.
//    include_plated_holes: default is false
//      Alternate version of the footprint compatible with side, reversible, hotswap, solder options in any combination.
//      Pretty, allows for connecting ground fill zones via center hole, 
//      allows for setting nets to Choc v2 stabilizers and them for your routing needs.
//    include_stabilizer_nets: default is false
//      if true, will add adjustable nets to choc v2 plated stabilizer holes, 
//      LEFTSTAB: default is "D1"
//      RIGHTSTAB: default is "D2"
//    include_centerhole_net: default is false
//      if true, will add adjustable net to the center hole
//      CENTERHOLE: default is "GND"
//    outer_pad_width_front: default 2.6
//    outer_pad_width_back: default 2.6
//      Allows you to make the outer hotswap pads smaller to silence DRC
//      warnings when the sockets are too close to the edge cuts. It's not
//      recommended to go below 1.6mm to ensure the hotswap socket can be
//      properly soldered.
//    include_keycap: default is false
//      if true, will add mx sized keycap box around the footprint (18mm)
//    include_corner_marks: default is false
//      if true, will add corner marks to indicate plate hole size and position
//    include_choc_v1_led_cutout_marks: default is false
//      if true, will add marks for the led cutout in choc v1 switch body
//    include_choc_v2_led_cutout_marks: default is false
//      if true, will add marks for the led cutout in choc v2 switch body
//    include_stabilizer_pad: default is true
//      if true, will add a corner pad for the stabilizer leg present in some
//      Choc switches, unless choc_v2_support is false.
//    oval_stabilizer_pad: default is false
//      if false, will add an oval pad for the stabilizer leg, and a round one
//      if true. Note that the datasheet calls for a round one.
//    choc_v1_stabilizers_diameter: default is 1.9 (mm)
//      Allows you to narrow Choc v1 stabilizer / boss holes diameter for tighter fit, not recommended to set below 1.7
//    choc_v1_support: default is true
//      if true, will add lateral stabilizer holes that are required for
//      Choc v1 footprints.
//    choc_v2_support: default is true
//      if true, will make the central hole bigger to as required for
//      Choc v2 footprints. If false it will also disable the corner stabilizer
//      pad even if include_stabilizer_pad is true.
//    keycap_height: default is 18
//      Allows you to adjust the width of the keycap outline. For example,
//      to show a 1.5u outline for easier aligning.
//    keycap_width: default is 18
//      Allows you to adjust the height of the keycap outline.
//    allow_soldermask_bridges: default is true
//      Disables 'solder mask aperture bridges items with different nets' DRC check when set to true
//      setting this option to false may be useful for debugging purposes, (applied locally to this footprint only)
//      for global setting see `allow_soldermask_bridges_in_footprints` in a kicad template
//    switch_3dmodel_filename: default is ''
//      Allows you to specify the path to a 3D model STEP or WRL file to be
//      used when rendering the PCB. Use the ${VAR_NAME} syntax to point to
//      a KiCad configured path.
//    switch_3dmodel_xyz_offset: default is [0, 0, 0]
//      xyz offset (in mm), used to adjust the position of the 3d model
//      relative the footprint.
//    switch_3dmodel_xyz_scale: default is [1, 1, 1]
//      xyz scale, used to adjust the size of the 3d model relative to its
//      original size.
//    switch_3dmodel_xyz_rotation: default is [0, 0, 0]
//      xyz rotation (in degrees), used to adjust the orientation of the 3d
//      model relative the footprint.
//    hotswap_3dmodel_filename: default is ''
//      Allows you to specify the path to a 3D model to be used when rendering
//      the PCB. Allows for paths using a configured path by using the
//      ${VAR_NAME} syntax.
//    hotswap_3dmodel_xyz_offset: default is [0, 0, 0]
//      xyz offset (in mm), used to adjust the position of the 3d model
//      relative the footprint.
//    hotswap_3dmodel_xyz_scale: default is [1, 1, 1]
//      xyz scale, used to adjust the size of the 3d model relative its
//      original size.
//    hotswap_3dmodel_xyz_rotation: default is [0, 0, 0]
//      xyz rotation (in degrees), used to adjust the orientation of the 3d
//      model relative the footprint.
//    keycap_3dmodel_filename: default is ''
//      Allows you to specify the path to a 3D model STEP or WRL file to be
//      used when rendering the PCB. Use the ${VAR_NAME} syntax to point to
//      a KiCad configured path.
//    keycap_3dmodel_xyz_offset: default is [0, 0, 0]
//      xyz offset (in mm), used to adjust the position of the 3d model
//      relative the footprint.
//    keycap_3dmodel_xyz_scale: default is [1, 1, 1]
//      xyz scale, used to adjust the size of the 3d model relative to its
//      original size.
//    keycap_3dmodel_xyz_rotation: default is [0, 0, 0]
//      xyz rotation (in degrees), used to adjust the orientation of the 3d
//      model relative the footprint.
//
// Notes:
// - Hotswap and solder can be used together. The solder holes will then be
//   added above the hotswap holes.
//
// @infused-kim's improvements:
//  - Add hotswap socket outlines
//  - Move switch corner marks from user layer to silk screen
//  - Add option to adjust keycap size outlines (to show 1.5u outline)
//  - Add option to add hotswap sockets and direct soldering holes at the
//    same time
//  - Make hotswap pads not overlap holes to fix DRC errors
//  - Fixed DRC errors "Drilled holes co-located"
//
// @ceoloide's improvements:
//  - Adjusted footprint to be Choc PG1353 (v2) compatible
//  - Add option to hide corner marks, as they interfere with hotswap silkscreen
//  - Add ability to specify board side
//  - Add ability to include stabilizer pad
//  - Add ability to use an oval stabilizer pad
//  - Add option to add routes between pads, and have pads on the same side
//  - Add option to lock routes between pads
//  - Upgrade to KiCad 8
//
// @grazfather's improvements:
//  - Add support for switch 3D model
//
// @nxtk's improvements:
//  - Add plated version, inspired by @daprice and @ssbb
//  - Add ability to adjust v1 stabilizer / boss holes
//  - Add ability to assign nets to v2 stabilizer / boss holes (useful for routing diode in place of backlight led)
//  - Add ability to set a net to central hole (useful for connecting ground fill zones)
//  - Add opposite stabilizer / boss holes when (choc_v2_support & solder & hotswap) options enabled together
//  - Change v2 stabilizer / boss holes to plated
//  - Add allow_soldermask_bridges option, which disables 'solder mask aperture bridges items with different nets' DRC check
//
// @mlilley's improvements:
//  - Add options to include marks for the led cutout in choc v1 and v2 switch bodies
