Subject: [PATCH] avoid redundant idle if using FRAME_SYNC to throttle

This updates the examples and test-journal which now use the _FRAME_SYNC
events to throttle rendering so that they don't install a redundant idle
handler to paint when they get a FRAME_SYNC event and instead they now
directly paint when the event is received.

(cherry picked from commit 579eb75e6ac6f50d7a9cfe5093435126158b3c96)
