Remove obsolete osg info
Support side-by-side installation of Qt4 and Qt5 builds
Use include/osgQt also for osgQt5
Sometimes, the window resized when _gw hasn't been created.
Fix bug when compiling the doc
fix the bug which _gw pointer is null.
If I hadn't call makeCurrent function before swapBuffers by using ThreadingModel::CullThreadPerCameraDrawThreadPerContext with Qt5.9, I will get this warning: qopenglcontext::swapbuffers() called without corresponding makecurrent().
This compiles but doesn't have an exmaple yet We use this in production for our software originale code is here https://github.com/mkrus/osgQt5Samples
fix bug: without corresponding makecurrent()
Modify FIND_PACKAGE Qt5 components
Added missing Camera::setDrawBuffer()/setReadBuffer()
Fix build with Qt 5.11_beta3 (dropping qt5_use_modules)
Compatible with the new and old versions of OSG
Feature/osgQOpenGL
* Removed definition of __gl_h_ to prevent the Gl.h include not defining standard Gl defines such as GLfloat when compiling on Windows systems (Visual Studio 2013 tested) * Removed setting of state settings specific to OpenGL 3 non fixed pipeline. * Added check for starting without any arguments to call constructor without arguments * Add setting of default fbo id to fix problem with render to texture in the QOpenGLWidget
"When implementing a new widget, it is almost always useful to reimplement sizeHint() to provide a reasonable default size for the widget and to set the correct size policy with setSizePolicy()." https://doc.qt.io/qt-5/qwidget.html#size-hints-and-size-policies Default value of QWidget::rect is 0,0,640,480. This SD aspect ratio agrees with OSG when widget is shown by itself. However, once widget is put into a layout it has to return a valid sizeHint in order to preserve this aspect ratio and size.
override sizeHint in osgQOpenGLWidget
Check the validation of `_mainwindow` when invoke `_mainwindow->setCentralWidget(this)`

Added setting of default fbo id to solve problem with rendering to texture. See http://forum.osgearth.org/solved-black-screen-with-drape-mode-in-a-QOpenGLWidget-td7592420.html#a7592421
