Orkuncakilkaya 259b4d9b35 fix(ui): 0.R4 - an action a UI button dispatches is reduced before the frame is presented
ludic.ui runs a frame's presses after drawing it, and what they dispatched waited for the end of the
phase - after the host had presented - so a button's change showed a frame late. Decided: drain, not a
phase per action. ui_show and ui_press drain the queue once the presses have run, so the code after
them and the frame presented next see the change; a host that runs presses some other way calls
drain_actions() before it presents.

bump: patch type: fix An action a UI button dispatches is reduced before the frame is presented. ludic.ui runs a frame's presses after drawing it, and an action they dispatched waited for the end of the phase - after the host had presented - so what the button changed showed a frame late. ui_show and ui_press now drain the queue once the presses have run. A host that runs presses some other way calls drain_actions() before it presents.
