Robert Osfield c07598dc39 From Hautio Jari, "Current version of GraphicsWindowWin32 allows resize to zero height 
window. This breaks rendering in for example MFC SDI applications and in
MFC MDI applications if user resizes the window so that client area has
zero height. Current safeguard for minimized window:

LRESULT GraphicsWindowWin32::handleNativeWindowingEvent( HWND hwnd, UINT
uMsg, WPARAM wParam, LPARAM lParam )
...
       /////////////////
       case WM_MOVE    :
       case WM_SIZE    :
       /////////////////
...
               if (clientRect.bottom==0 && clientRect.right==0)
...

does not cover this situation. In these situations clientRect.bottom = 0
and clientRect.right > 0.

Quick fix to this is relax condition:
               if (clientRect.bottom==0 || clientRect.right==0)

Modified file is attached.

Tested with osgviewerMFC from 2.2.0 release (Windows XP sp2)

Before fix:
 - execute from command line osgviewerMFC.exe cow.osg.
 - the cow is rendered nicely.
 - resize window to zero height by dragging from bottom border upwards.
 - resize window back to original height
 - just blue screen, no cow

After fix:
 - execute from command line osgviewerMFC.exe cow.osg.
 - the cow is rendered nicely.
 - resize window to zero height by dragging from bottom border upwards.
 - resize window back to original height
 - the cow is where it is supposed to be.

Welcome to the OpenSceneGraph (OSG).

For up-to-date information on the project, in-depth details on how to 
compile and run libraries and examples, see the documentation on the 
OpenSceneGraph website:

How to build the OpenSceneGraph
===============================

The OpenSceneGraph uses the CMake build system to generate a 
platform-specific build environment.  CMake reads the CMakeLists.txt 
files that you'll find throughout the OpenSceneGraph directories, 
checks for installed dependenciesand then generates the appropriate 
build system.

If you don't already have CMake installed on your system you can grab 
it from http://www.cmake.org, use version 2.4.6 or later.  Details on the 
OpenSceneGraph's CMake build can be found at:

    http://www.openscenegraph.org/projects/osg/wiki/Build/CMake

Under unices (i.e. Linux, IRIX, Solaris, Free-BSD, HP-Ux, AIX, OSX) 
use the cmake or ccmake command-line utils, or use the included tiny 
configure script that'll run cmake for you.  The configure script 
simply runs 'cmake . -DCMAKE_BUILD_TYPE=Release' to ensure that you 
get the best performance from your final libraries/applications.
 
    cd OpenSceneGraph
    ./configure
    make
    sudo make install
  
Alternatively, you can create an out-of-source build directory and run 
cmake or ccmake from there. The advantage to this approach is that the 
temporary files created by CMake won't clutter the OpenSceneGraph 
source directory, and also makes it possible to have multiple 
independent build targets by creating multiple build directories. In a 
directory alongside the OpenSceneGraph use:

    mkdir build
    cd build
    cmake ../OpenSceneGraph -DCMAKE_BUILD_TYPE=Release
    make
    sudo make install

Under Windows use the GUI tool CMakeSetup to build your VisualStudio 
files. The following page on our wiki dedicated to the CMake build 
system should help guide you through the process:

    http://www.openscenegraph.org/projects/osg/wiki/Support/PlatformSpecifics/VisualStudio

Under OSX you can either use the CMake build system above, or use the 
Xcode projects that you will find in the OpenSceneGraph/Xcode 
directory.

For further details on compilation, installation and platform-specific 
information read "Getting Started" guide:
