[Haskell-cafe] ANN: OpenGL packages update

The updates include: * All of the newtypes in OpenGLRaw have been changed to type aliases (credit to Trevor Elliott and Mike Ledger) * OpenGLRaw's TypesInternal module has gone away * NVidia path rendering extensions have been added by "ozelis" on github This release changes OpenGLRaw to use type aliases instead of newtype wrappers for the GLfoo types, such as GLenum/GLfloat/GLdouble. Using newtypes had the following downsides: * The CPP macros to make these definitions are borrowed verbatim from GHC sources and required updates with new GHC releases in order to stay compatible. Although, it hasn't been a problem yet, it's conceivable this will conflict with supporting different versions of GHC at some point. * Optimization rules have to be written against these newtypes and forgetting them can lead to significant performance degradation or extra verbosity for people using the bindings. * You have to reach pretty deep into GHC to make it possible for the newtypes to work in the unboxed vectors provided by the vector package. This is again, another missed opportunity for high performance code.
