Description of problem:
glxinfo does not report multisample capable visuals because of a logic error in
the code.

Version-Release number of selected component (if applicable):
MesaDemos-6.5.2

How reproducible:
Just use glxinfo with a video card that supports multisampling (nvidia)

Steps to Reproduce:
1. glxinfo
2.
3.
  
Actual results:
always shows number of samples and number of buffers as zero

Expected results:
should show the correct values

Additional info:
Basically, the following line in the code:

   if (ext && strstr(ext, "GLX_ARB_multisample") ) == 0) {

might be changed to:

   if (ext && strstr(ext, "GLX_ARB_multisample") ) {

The code is checking for the opposite of what is desired.


Basically,
