I don't want to start any type of argument, but let's pretend for a second
that I don't actually know what each and every possible configuration option
does and so I need to depend on the help from the "configure" script. So
using "configure --help" I see the following:

    -graphicssystem <sys> Specify which graphicssystem should be used.
                          Available values for <sys>:
 *                         raster - Software rasterizer
                           opengl - Using OpenGL acceleration, experimental!
                           openvg - Using OpenVG acceleration, experimental!

Now, since I am creating a program that displays very large images (10k x
10k pixels) i certainly don't want the "raster - Software Rasterizer". The
Next option, "opengl" looks the best but the whole "this is experimental"
scares me. After looking through some example code I got the idea that not
all Windows systems would have opengl available/enabled so some googling
comes up with "-graphicssystem=runtime" with no context to tell me that it
should be MeeGo/Symbian. Working with Visual Studio 2008 all works just
fine. So take the same settings from VS 2008 and try and build with VS2010.
That is my story of how I got there.
  What would have helped me forgo this "problem"? Maybe an update to the
"configure" script to actually list the "runtime" option and how it is ONLY
for MeeGo/Symbian. That much would have at least made me think twice before
actually configuring Qt with that option on my own system.

  I do appreciate your help with this. As always, keep up the great work.
