Handle Mac coordinate flip in CairoQuartzSurface

These changes are associated with commit 549d208 in the Tk package.

This simplifies things greatly, because Tk widgets also get flipped with the old way of doing things.  We now flip the y axis when making a Cairo Quartz surface, then flip back immediately afterwards.  The initial graph in Winston is upside down, but corrects itself on a resize.  I think this remaining bug is related to the order of callbacks, which I haven't quite figured out yet.

Some changes to make Cairo work on mac.
remove all references to Mac coordinate flip (reverts 7a60821 and
related and moves the necessary code back to Tk.jl)
fix a pointer truncation in cairo_xlib_surface_create (XID is a unsigned long)
fix find_library usage to remove deprecation warnings
Use zlib 1.2.8. Fix #23.
I am not updating the SHA1, as someone should verify this does work.
