Hi all-

Is there a way to draw a vector with flipped axes? In the example, the vectors are drawn in two places (and without an error in the correct place).

```
using Plots
m1 = (x=350,y=250)
m2 = (x=375,y=26)
vm = (x=m1.x-m2.x, y=m1.y-m2.y)
vt = (x=0,y=1)
scatter([m1.x], [m1.y], ylims=(0,500), xlims=(0,700),
leg=false, color=:black, markersize=8, yaxis=:flip)
scatter!([m2.x], [m2.y], markersize=8, color=:darkred)
quiver!([m2.x], [m2.y], quiver=([100],[0]))
```
