16 bpp video stream capture, render and createImageBitmap(video) using (CPU) shared memory buffers
This patch implements support for depth capture on Windows/Linux and ChromeOS using shared
memory buffers. WebGL implementation with no precision loss and GPU memory buffer usage is
split to separate patches from master patch: crrev.com/2121043002/
It Supports 16 bit depth video streams from R200 and SR300.
Verified to work on Windows 10 and Ubuntu 16.04.
Rendering video element:
In cc, it is converted to RGBA format before glTexImage2D and rendered as TexturedQuad.
2D canvas + getImageData returns 8 bit color components (higher bit value) in RGBA.
