Matches HID device to the descriptor.

Helper; returns true if args match our enumeration criteria.

Case insensitive compare implemented in platform-specific way.

Parses a hex string up to the specified number of digits. Returns the first character after the string.

Get the previous (left) sibling node of this node.

----------------------------------------------------------------------------- Render a value to text.

Projects this vector onto a plane defined by a normal vector

Set and then reset an event once a waiter is released. If threads are already waiting, they will be notified and released If threads are not waiting,

Compute a rotation required to transform "estimated" into "measured" Returns an approximation of the goal rotation in the Simultaneous Orthogonal Rota

Aspect ratio defaults to ((w/h)*multiplier) computed per eye. Aspect multiplier allows adjusting aspect ratio consistently for Stereo/NoStereo.

Declare whether this should be CDATA or standard text.

Set an event, releasing objects waiting on it

Enables/disables gravity correction (on by default).

Enables/disables magnetometer based yaw drift correction. Must also have mag calibration data for this correction to work.

Loads and stores with memory fence. These have only the relevant versions.

Safely cast to a Comment, or null.

----------------------------------------------------------------------------- Parses the input text into a string item and returns the text position a

Notifiers called when we are added to/removed from a device.

Append the given data to the array.

StereoParams apply Viewport, Projection and Distortion simultaneously, doing full configuration for one eye.

Apply "orthographic" stereo parameters used for rendering 2D HUD overlays.

We don't need there on Manager since it isn't assigned to DeviceHandle.

Returns conjugate of the quaternion. Produces inverse rotation if quaternion is normalized.

Callbacks for DeviceCreation/Release

DistortionFn applies distortion equation to the argument. The returned value should match distortion equation used in shader.

Lock and try lock

Dot product Used to calculate angle q between two vectors among other things, as (A dot B) = |a||b|cos(q).
