Ryan Pavlik 928254ffed a/math: Add a rational number struct template. 2022-02-22 09:58:19 -06:00
Mateo de Mayo 4b94d83c11 a/math: Fix one euro implementations not dividing by dt 
The dy name was kept. It can now be thought of as "[d]erivative of [y]"
instead of the previous "change of y". Also, the beta parameters of the
one-euro users were adjusted by approximately multiplying them by 0.016
to compensate.

Ryan Pavlik 33c0287f8b xrt: Rename all "num" parameters and fields to "count" (or "capacity" as appropriate) 
This matches the OpenXR usage: the array is the plural of the element type,
and the count is the singular element type plus "count" (usually CountOutput
because of the two-call idiom)

Includes fixes to other code to match API changes.
