v0.1.28

Face buttons: X and Y now use the codes SDL expects for non-Sony controllers

X emits BTN_NORTH (0x133) and Y emits BTN_WEST (0x134) whenever the [output]
vendor id is not Sony (0x054c); Sony identities keep X = BTN_WEST.

Affected shipped configs: 8bitdo ultimate, flydigi vader4-pro and its
04b4:2412 variant, hori horipad-steam, lenovo legion-go, microsoft xbox-elite,
valve steam-deck. Affected presets: xbox-360 and xbox-elite2.

To keep the previous behaviour, declare X = "BTN_WEST" and Y = "BTN_NORTH"
in your own config. If you compensated with a Steam Input layout or an
in-game rebinding, undo it, otherwise X and Y swap a second time.
Old-style configs still load; padctl logs one warning.

Other changes

• A dpad hat-switch field now reaches the output d-pad and takes part in
  remap, layers, arrows mode and suppress_gamepad like button-bit d-pads.
  Declaring both a dpad field and DPad* button bits is rejected.
• bits fields accept a transform chain; scale uses the declared bit
  width as full scale, so a 10-bit trigger can be declared as
  rt = { bits = [4, 6, 10], transform = "scale(0, 255)" }.
