[PD] pizza slice in gem

[glerm soares]

hey,

I was thinking about how to do a graphic "knob" with this patch, but could
not realize yet the correct trigonometric operation to do with [gemouse]
transformations... Could someone give an idea? I though in something like
the edge of the angle stucked in the mouse pointer, but I don't know Gem or
geometry enough to realize it...


the starting point is attached...

thanks
glerm
