* This file should be included as

* khronos_int16_t signed 16 bit
* khronos_uint16_t unsigned 16 bit

* khronos_int64_t signed 64 bit
* khronos_uint64_t unsigned 64 bit
* khronos_intptr_t signed same number of bits as a pointer
* khronos_uintptr_t unsigned same number of bits as a pointer
* khronos_ssize_t signed size
* khronos_usize_t unsigned size
* khronos_float_t signed 32 bit floating point
* khronos_time_ns_t unsigned 64 bit time in nanoseconds
* khronos_utime_nanoseconds_t unsigned time interval or absolute time in
* nanoseconds
* khronos_stime_nanoseconds_t signed time interval in nanoseconds
* khronos_boolean_enum_t enumerated boolean type. This should
* only be used as a base type when a client API's boolean type is
* an enum. Client APIs which use an integer or other type for
* booleans cannot use this as the base type for their boolean.
*
* Tokens defined in khrplatform.h:
*
* KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.
*
* KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.

/*
Original Lens Distortion Algorithm from SSontech
http://www.ssontech.com/content/lensalg.htm
If (u,v) are the coordinates of a feature in the undistorted perfect
image plane, then (u', v') are the coordinates of the feature on the
distorted image plate, ie the scanned or captured image from the
camera. The distortion occurs radially away from the image center,
with correction for the image aspect ratio (image_aspect = physical
image width/height), as follows:
r2 = image_aspect*image_aspect*u*u + v*v
f = 1 + r2*(k + kcube*sqrt(r2))
u' = f*u
v' = f*v
The constant k is the distortion coefficient that appears on the lens
panel and through Sizzle. It is generally a small positive or negative
number under 1%. The constant kcube is the cubic distortion value found
on the image preprocessor's lens panel: it can be used to undistort or
redistort images, but it does not affect or get computed by the solver.
When no cubic distortion is needed, neither is the square root, saving
time.
Chromatic Aberration example,
using red distord channel with green and blue undistord channel:
k = vec3(-0.15, 0.0, 0.0);
kcube = vec3(0.15, 0.0, 0.0);
