Since it was reverted long time ago, reimplement it from the scratch.

HW decoded video is blurry, because crbug.com/575587 shinked visual rect by 1
pixel, if coded rect is larger than visual rect. This fixed bleeding texture,
but caused blurry issue.

Meanwhile, crbug.com/429640 fixed bleeding texture for software YUV video in
the elegant way. It clamps all texture coordinates to this maximum value in the
fragment shader.

This CL removes the 1 pixel hack and applies the way to TextureDrawQuad and
StreamVideoDrawQuad.

In addition, Video overlay requires this fix because there is noticible
transition between GPU composition and hardware overlay.
