Hi 

I am experimenting with various rasterizing algorithms and up to now I
was using banked modes under VESA (DOS). Now  when I wanted to implement
symmetric line algorithms, bank switching slows down algorithm,
incredibly. Linear frame buffer should solve the problem, but it seems
that it requires lots of messing with DOS internals (real, protected
mode) and I really  do not want to that. 

My question is LFB programming under Linux more enjoyable ( less messy)? 
Moreover, does memory handling under Linux using GNU C++ suffers form
any of GNU C++/DOS illnesses such as: weird memory-handling functions or
libraries, various memory organisations, DPMI, etc. ?

Thank you

Ivan
