+ Definitions:
+ v - speed in steps per pixeltime
+ w - speed in pixel times per step. w = 1 / v
+ a - acceleration in steps per pixeltime squared
+ s - distance travelled in steps
+ t - time in pixeltime
+
+ The physical mode defines the curve in physical quantities. We asssume that the scanner head
+ accelerates from standstill to the target speed uniformly. Then:
+
+ v(t) = v(0) + a * t (2)
+
+ Where `a` is acceleration, `t` is time. Also we can calculate the travelled distance `s`:
+
+ s(t) = v(0) * t + a * t^2 / 2 (3)
+
+ The actual motor slope is defined as the duration of each motor step. That means we need to
+ define speed in terms of travelled distance.
+
+ Solving (3) for `t` gives:
+
+ sqrt( v(0)^2 + 2 * a * s ) - v(0)
+ t(s) = --------------------------------- (4)
+ a
+
+ Combining (4) and (2) will yield:
+
+ v(s) = sqrt( v(0)^2 + 2 * a * s ) (5)
+
+ The data in the slope struct MotorSlope corresponds to the above in the following way:
+
+ maximum_start_speed is `w(0) = 1/v(0)`
+
+ maximum_speed is defines maximum speed which should not be exceeded
+
+ minimum_steps is not used
+
+ g is `a`
+
+ Given the start and target speeds on a known motor curve, `a` can be computed as follows:
+
+ v(t1)^2 - v(t0)^2
+ a = ----------------- (6)
+ 2 * s
+
+ Here `v(t0)` and `v(t1)` are the start and target speeds and `s` is the number of step required
+ to reach the target speeds.
