|
* This file is a reduced version of the header file of

* <X11/xpm.h>
|
|
*
|
|
* This copy of code has been introduced to allow a clear namespace
|
|
* separation between <X11/...> and <nx-X11/...> header files.
|
|
*
|
|
* This version of the Xpm library header file only contains symbols
|
|
* required by nxagent and strictly avoids indirectly including
|
|
* from an X11 library that is also shipped in nx-X11/lib/.
|
|
*
|
|
* When using <X11/xpm.h> instead for inclusion in nxagent, it will
|
|
* attempt pulling in the <X11/extensions/Xlib.h> header file.
|
|
* However, the headers of the same name from <nx-X11/...> should be
|
|
* used instead.
|
|
*
|
|
* FIXME: Once the nxagent Xserver starts using libX11 from X.Org, this
|
|
* hack can be removed.
