 .SH TABLET TOOL AREA RATIO
 By default, a tablet tool can access the whole sensor area and the tablet

+For external tablets like the Wacom Intuos series,
+the height:width ratio of the tablet may be different to that of the monitor,
+causing the skew of input data.
 .PP
 To avoid this skew of input data, an area ratio may be set to match the
-ratio of the screen device. For example, a ratio of 4:3 will reduce the
-available area of the tablet to the largest available area with a ratio of
-4:3. Events within this area will scale to the tablet's announced axis
-range, the area ratio is thus transparent to the X server. Any events
-outside this area will send events equal to the maximum value of that axis.
-The area always starts at the device's origin in it's current rotation, i.e.
+ratio of the screen device.

+.SH SCROLL PIXEL DISTANCE
+The X server does not support per-pixel scrolling but it does support
+smooth scrolling.
+All scroll events however are based around a logical unit of scrolling
+(traditionally corresponding to a wheel click).
+It is thus not possible to scroll by 10 pixels, but it is possible for a
+driver to scroll by 1/10th of a logical wheel click.
+.PP
+libinput provides scroll data in pixels.
+The \fBScrollPixelDistance\fR option defines the amount of movement equivalent
+to one wheel click.
+For example, a value of 50 means the user has to move a finger by 50 pixels to
+generate one logical click event and each pixel is 1/50th of a wheel click.
+
+.SH CUSTOM ACCELERATION PROFILE
+The custom pointer acceleration profile gives users full control over the
+acceleration behavior at different speeds.
+libinput exposes an acceleration function \fIf(x)\fP
+where the x-axis is the device speed in device units per millisecond
+and the y-axis is the pointer speed.
+.PP
+The custom acceleration function is defined using n points which are spaced
+uniformly along the x-axis, starting from 0 and continuing in constant steps.
+Thus the points defining the custom function are:
+.EX
+(0 * step, f[0]), (1 * step, f[1]), ..., ((n-1) * step, f[n-1])
+.EE
+When a velocity value does not lie exactly on those points,
+a linear interpolation/extrapolation of the two closest points
+will be calculated.
+.PP
+There are 3 custom acceleration functions,
+which are used for different movement types:
