Christoph Haag e785053c0a aux/math: special case delta_s == 0 in m_predic 
Rather than asserting in the underlying math functions we return the
trivial values for prediction with 0s.

Jakob Bornecrantz 1e4a540bb9 aux/math: Add prediction module 
For the time being all angular velocities are relative to the space a xrt_space_relation is in.

Christoph Haag fb71c71a8c xrt: Replace mesh generator with xdev->compute_distortion() 
Each HMD driver now has to implement compute_distortion() which will be called
by the compositor implementation to generate a mesh (usually).

u_distortion_mesh contains implementations for the defaults (panotools, OpenHMD, vive).

Also adds compute_distortion function for Vive distortion

There are differences between OpenHMD and Panotools values, main differences for now:
* psvr has 5 pano coefficients, ohmd has 3
* psvr uses viewport size and lens center in pixels for distortion calculation, ohmd in meter
* psvr uses different distortion scaling than ohmd

Christoph Haag 1429d678a0 aux/space: Propagate orientation valid bit through space graph resolve 
Invalid poses may be handled more gracefully in the future. For now poses
are not transformed if orientation is not valid, because transforming with
an invalid quaternion will have bad results in any way.

v2: Upgrade poses with valid position but invalid orientation to valid poses

Christoph Haag 7a1dbbe8a1 st/oxr: Ensure quaternion is normalized in xrLocateViews() 
In rare cases the state tracker's pose transformations resulted in a quaternion
that accumulated float precision errors such that the norm of the quaternion was
not within float precision of 1.0 anymore.

Introduce a function math_quat_ensure_normalized() that can be used after multiple
operations have been performed on a quaternion.

Jakob Bornecrantz 9d791cdfd3 math: Use non-squared 'length' of quat in validation 
Correctly validate quaternion using non-squard "length" instead of squard
"length", certain combinations of elements would produce valid regular "length"
but not valid squard ones.
