Zero-initialize the context state and data

Using an initialization method or in-class initialization of each member
is bug-prone. Zero-initialization performed by the default constructor
guarantees repeatability.

Also don't skip drawing when the multisample mask is zero. Pipeline
stages prior to fragment processing may have side-effects.
