Name
ccontext:DeviceToUserDistance -- device to user distance
Synopsis
ux, uy = ccontext:DeviceToUserDistance(dx, dy)
Function
Transform a distance vector from device space to user space. This function is similar to ccontext:DeviceToUser() except that the translation components of the inverse CTM will be ignored when transforming (dx, dy).

Inputs
dx
X component of a distance vector (device space)
dy
Y component of a distance vector (device space)
Inputs
ux
X component of a distance vector (user space)
uy
Y component of a distance vector (user space)
