Dropping in the discussion;

You might want to compare official code with hg-povray code for display 
( https://github.com/LeForgeron/povray/tree/hgpovray38/unix )
as I made a port for libsdl2 and raw X11 (but you cannot compile for 
both libsdl 1.2 and libsdl 2.0, they are using the same API with 
different interfaces (they fucked it))

IIRC, libdsl2 is far better that 1.2
