scroll direction not propagated in backend_kivy.py

[SStarosielec]

I'm sorry I don't know the proper etiquettes to report bugs. I've tracked down a bug that doesn't allow me to process scroll events with proper direction.

In these two lines

garden.matplotlib/backend_kivy.py

Line 1120 in 121788c

if 'button' in touch.profile and touch.button in ("scrollup", "scrolldown",):

garden.matplotlib/backend_kivy.py

Line 1172 in 121788c

if 'button' in touch.profile and touch.button in ("scrollup", "scrolldown",):

if 'button' in touch.profile and touch.button in ("scrollup", "scrolldown",):
                self.scroll_event(x, y, 5, guiEvent=None)

the scroll direction is encoded in the step size sign, but both directions are set to +5.

That conflicts with the convention in "backend_bases.py" L1775

        if step >= 0:
            self._button = 'up'
        else:
            self._button = 'down'

I fixed my local copy, but not sure how to proceed on github.

I've had this same issue. I'm not completely clear on how you fixed it. Could you elaborate what changes you made?
