Important: xorg-x11-server

Issue Overview: The ProcRenderAddGlyphs function calls the AllocateGlyph function to store new glyphs sent by the client to the X server. AllocateGlyph would return a new glyph with refcount=0 and a re-used glyph would end up not changing the refcount at all. The resulting glyphnew array would th...
