Ok but for a GWT Canvas there is no canvas.getBoundingClientRect() or
similar.
So this would mean I have to constantly update the mouseXY variables within
@UiHandler("canvas")
void onMove(MouseMoveEvent evt) {
x = evt.getRelativeX()...
}
BUT wouldn't this add a big overhead in the long run if I constantly
rewrite the coordinates?
I could of course use some timer to update XY, but this would then again
result in inaccurate coordinates if the keypress comes in the wrong moment.
