Digitizer HID interface : absolute coordinates for mouse cursor (#12851)
* Add digitizer HID interface for setting the mouse cursor position at absolute screen coordinates. Tested on Pro Micro, Proton C and Blackpill. * Update docs/feature_digitizer.md Co-authored-by: Ryan <fauxpark@gmail.com> * Update tmk_core/protocol/usb_descriptor.c Co-authored-by: Ryan <fauxpark@gmail.com> * Add missing copyrights Add V-USB support * Add support for digitizer dedicated endpoint for lufa and chibios. Fix formatting issues Move digitizer_task definition to the feature's base implementation file * Run cformat on modified files * Change digitizer report usage to Digitizer instead of Pen to avoid pointer disappearing on Windows. * Update tmk_core/protocol/vusb/vusb.c Co-authored-by: Ryan <fauxpark@gmail.com> * Run cformat from docker image * Remove send_digitizer from host_driver_t and instead rely on the declaration being the interface to the implementation in each HW-specific usb implementation. * Fix build : send_digitizer shouldn't be static in vusb and add weak-linkage implementation for tests without usb implementation * Change digitizer user interface to match pointing device's * Update documentation with new API Co-authored-by: a-chol <nothing@none.com> Co-authored-by: Ryan <fauxpark@gmail.com>
