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.

Include <inttypes.h> to satisfy older compilers
 2020-10-12 22:13:47 +02:00
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
