gui_toolkit 0.47.0

Fixed

• A drag inside the window is shown at the top rate of a variable refresh screen (platform.frame_decision, Cadence.variable, platform.cadence_adopt): on a variable refresh screen (G-Sync, FreeSync, Windows' dynamic refresh rate, which reports 60 Hz at rest), a Drag frame (a splitter, a panel's handle, a tab) is presented at once with two frames queued, still one frame per slot of the top rate, instead of waiting for a refresh at the rate the screen rests at: a splitter dragged at 1 kHz went from 62 to 183 frames a second on a 180 Hz screen reported at 60 Hz. Fixed refresh screens and every other state are unchanged. cadence_adopt(&c, plan) takes the plan's slots and screen (instead of c.slots = plan.slots).
