commit 171769f64d2380be763c8ae5e9523cbb2c81f17f

Validate texture target before updating texture size.

The target was validated that it was one of the TextureTarget types but
not that the type was valid for the current context.  This generated GL
errors when querying the size of a 3D texture in an ES2 context.
