fltk/FL/Fl_Double_Window.H
Albrecht Schlosser f09e17c3c5 Remove $Id$ tags, update URL's, and more
- remove obsolete svn '$Id$' tags from all source files
- update .fl files and generated files accordingly
- replace 'http://www.fltk.org' URL's with 'https://...'
- replace bug report URL 'str.php' with 'bugs.php'
- remove trailing whitespace
- fix other whitespace errors flagged by Git
- add and/or fix missing or wrong standard headers
- convert tabs to spaces in all source files

The only relevant code changes are in the fluid/ folder where
some .fl files and other source files were used to generate
the '$Id' headers and footers.

/**
The Fl_Double_Window provides a double-buffered window.
If possible this will use the X double buffering extension (Xdbe). If
not, it will draw the window data into an off-screen pixmap, and then
copy it to the on-screen window.
<P>It is highly recommended that you put the following code before the
first show() of <I>any</I> window in your program: </P>
\code
Fl::visual(FL_DOUBLE|FL_INDEX)
\endcode
This makes sure you can use Xdbe on servers where double buffering
does not exist for every visual.
