Use a small threshold for numerical stability for rotation_center

Remove accidentally added include/grail.h.orig file

Was added in commit 148

Use a red dot to denote the pivot point

The pivot point is also now drawn after the touches so it is visible when
on top of a touch point. Some drawing code was simplified by using
clear_screen.

Fix transformation calculation so it uses the centroid correctly

Rework grail pivot/anchor point calculation and data

Instead of having a "pivot" point, use the centroid as the anchor point
for the transformation matrix, and calculate the center of rotation as a
separate value. This should help remove some ambiguity about what the
pivot meant.

As a consequence, the moveness value has been removed and we no longer
confine the transformation anchor point to an approximation of the convex
hull of the touches. This eliminates the scaling and dragging threshold
controls as well.

Update copyright information

The license information was always right, but the copyright information
for this particular project was never quite right. Corrected with this
patch. No functional changes.

Introduce the grail transform tool

This tool tests the transform capabilities of grail. Similar to a
map application, one can use a single finger, two fingers, a whole
hand or two hands to move the rectangle around, scale and rotate it.
