I feel like feed rate should consider both vertical and horizontal rates when making a move that's a ramp. Currently I see that the G-code generated picks one or the other feed rate rigidly.
A simplified example situation:
Horizontal feed rate: 20mm/s
Vertical feed rate: 5mm/s (plunge rate)
Contour cut around a box with a helix ramp entry dress-up.
My expectation:
Horizontal feed at (or near) 20mm/s. This is mostly a horizontal cut with a gradual ramp into the material.
Actual behavior:
5mm/s feed rate even though it's mostly horizontal motion.

The behavior is the same for many other moves that change Z; it's not confined to ramp dress-up.
