This class provides an basic ancestor for classes implementing dump
backends, providing a light public API. The goal of this API is to be "just
enough", not a generic writing solution. To that end it provides the
method, 'dump'. This method is designed to be just enough to write a

This method takes keyword arguments that define options for the

apitrace_*, while a file gfxrecon value should be passed as gfxrecon_*)

images.
