Is your feature request related to a problem? Please describe.
I am using https://github.com/kando-menu/kando/, which i trigger using 1-tap-hold which triggers Ctrl+Space using ydotool, the problem is after that tap-hold i have to hold CTRL manually from keyboard to go into https://kando.menu/usage/#turbo-mode or use tap-down-up-down-move-up for https://kando.menu/usage/#marking-mode.

If fusuma supported hold-drag gesture having begin:, update:, end then i will be able to send Ctrl+Space then hold-Ctrl using ydotool in the begin section and release Ctrl in the end section.

Describe the solution you'd like
hold-drag gesture support, where i can hold then move my finger across trackpad and when i release the finger off the trackpad the gesture completes. It will support begin:, update:, end:

Describe alternatives you've considered
Currently i can use 3,4 finger swipe. But this gets congested on touchpad as in kando there are levels of submenu. Also i wanna free 3,4 swipe for others like workspace management.

Additional context
In the output of libinput debug-events --verbose there's a log for when user lifts fingers off the touchpad -->

404: event8  - button state: touch 0 from BUTTON_STATE_AREA    event BUTTON_EVENT_UP          to BUTTON_STATE_NONE
  ... event8  - gesture: [1fg] event GESTURE_STATE_POINTER_MOTION → GESTURE_EVENT_END → GESTURE_STATE_NONE

If the above is possible then can it be extended to 2-finger-hold-drag and 3-finger-hold-drag? For example we can use the following events for 3-finger-hold-drag -->
event8 GESTURE_HOLD_BEGIN +0.236s 3
event8 GESTURE_HOLD_END +1.215s 3 cancelled
event8 POINTER_MOTION +1.218s -1.45/ 0.12 (-12.00/ +0.97)
event8 POINTER_MOTION 2 +1.225s -4.87/ 0.29 (-16.00/ +0.97)
event8 POINTER_MOTION 3 +1.232s -5.43/ 0.33 (-16.00/ +0.97)
event8 POINTER_MOTION 4 +1.239s -6.79/ 0.00 (-20.00/ +0.00)
event8 POINTER_MOTION 5 +1.246s -7.81/ 0.00 (-23.00/ +0.00)
143: event8 - button state: touch 1 from BUTTON_STATE_AREA event BUTTON_EVENT_UP to BUTTON_STATE_NONE
... event8 - gesture: [1fg] event GESTURE_STATE_POINTER_MOTION → GESTURE_EVENT_END → GESTURE_STATE_NONE

i.e we start with 3 tap hold then lift two finger up and keeping one finger still on trackpad start moving on the trackpad.

Edit: make the above example more clear.
