[lazarus] How to disable double buffering

[Mattias Gaertner]

Hi all,

The recently added double buffering for the ExtTextOut function reduced the
flickering for the price, that on some machines the source editor became 20
times slower and thus unusable.
The democratic (demo=devels) decision was to keep the new "double" buffering
as default. ;(

For all those, who don't have fast computers: you can disable the buffering
by compiling with -dDisableDoubleBuf flag.

If no one implements a nicer solution in the next week, I think, it will be
best to implement this as a command line parameter or an editor option.
