Example rationale

OGLplus does not officially provide means for creating of the default framebuffer nor any code related to window-system or user-input.

The example code is usually encapsulated in a class derived from the Example class and the build system selects and builds and links the piece of code doing the initial setup, cleanup and handling of events to the example code automatically. This way the examples are not too cluttered by things which are not directly related to OpenGL® and OGLplus usage. The examples are numbered and ordered roughly by their "difficulty", from the easiest to the most complex.

In the example directory there are however also several standalone examples, showing complete applications which also contain the initialization and cleanup code, using various libraries like GLUT, GLEW, etc.
