51645accac Protected +initialize from being called multiple times on GSContext because of 
subclasses. 

As a result, this eliminates a gstate table memory leak, and prevents the table 
to be reset while still in use (causing various DPS errors such as invalid 
param, stack underflow and segfault).

Add a new interface, GSShowGlyphsWithAdvances, which replaces
GSShowGlyphs as the primitive text drawing method.

None of the backends implement it properly yet; I simply renamed
the existing -GSShowGlyphs:: methods to -GSShowGlyphsWithAdvances:::,
so they currently ignore the glyph advances.

b53fe57e7c Fixed many drawing issues (many ones being related to the flipping). 
See bug report #27782

In particular, fixed -[NSImage drawXXX] and -[NSImage composite/dissolveXXX] 
methods to work exactly as Cocoa when the Cairo backend is used.
Added a new draw operator (in addition to composite) to the backend. Cairo is 
the only backend that implements it for now.
Eliminated as many flipping checks as possible.

Warning: Untested with the winlib backend. 
You must update, recompile and install both Back and Gui.
