Detailed Description

An Impeller Android context that dynamically creates either an [AndroidContextGLImpeller] or an [AndroidContextVKImpeller].

The construction of these objects is deferred until [GetImpellerContext] is invoked. Up to this point, the reported backend will be kImpellerAutoselect.
