stop passing |level| to WebGraphicsContext3D

|level| is no longer used as a result of crbug.com/443151.
So currently video canvas painting is broken as the call has an empty implementation.

PTAL

Argh! Thank you for tracking this down. LGTM

Will this be covered by any of the WebGL conformance tests? Can or should we
upgrade
http://build.chromium.org/p/chromium.gpu/builders/Android%20Debug%20%28Nexus%...
to Android L to be able to re-enable the video tests?
