[chromium] Compositor needs to set texture filtering on canvas layers

Other layers (WebGL, plugin) set texture filtering to linear.  The canvas layer just takes whatever's on the texture it's been given, which happens to be linear.  Set it explicitly instead.

R=me, but it seems a bit silly to do it here. tex parameters are associated with the texture, not a particular binding, so we should only do this once when we create the texture.

I'm not totally convinced of that.  When canvas switches to using a ManagedTexture, it's possible that its texture could be recycled from some texture that has different settings.

In that case the recycling should preserve any texParameters. I agree that it probably doesn't today (grumble about crappy recycling code).
