+/* Raster says -
+4. evas exposes an opengl-es2 api. any existing engine needs to be adapted to
+use this. that's pretty much the end of that. if the engine doesn't have a
+gles2 port.. it will need one. once it has one, then it is a simple matter of
+replacing all the gl calls as follows:
+
+glDrawArrays() -> api->glDrawArrays()
+glBindBuffer() -> api->glBindBuffer()
+
+you could make the port switchable with a macro:
+
+#ifdef EVASGL
+#define EG() my_evas_gl_api->
+#else
+#define EG()
+#endif
+
+then fix up all the gl calls to be
+
+EG()glDrawArrays()
+EG()glBindBuffer()
+
+etc.
+
+doing the above allows evas to decide how to share context. it may allocate a
+separate context or share its own. either way as far as the evasgl api user is
+concerned.. they get their own private context to play with. if it does NOT do
+the above (use the api exposed by evas gl) then wrapping can't context switches
+can't work. all gl calls HAVE to go through the wrapped api to work right. this
+is because we can't REPLACE the internals of the gl driver which otherwise
+would be managing context and state all internally and we have zero access to
+that - especially with closed drivers. we'd end up writing a proxy gl library
+which conflicts with real gl symbol-wise (thus taking over and replacing
+normal gl calls) and i know i have no interest in maintaining a separate
+libGLwhatever.so that is an exact copy of gl and it's api's just to wrap it
+when we expose that wrapper without symbol complications via evas gl.
+
+5. the engine will need to be adapted so the draw function is callable - eg by
+elm_glview. then it's easy to switch where rendering happens. evas offers a fast
+path to avoid buffer copies and make the gl view draw part of the evas
+rendering path directly. this would offer almost zero overhead vs doing it
+directly with egl/gles etc. to your backbuffer yourself, BUT gets you the bonus
+of having your 3d view as part of a larger scenegraph. combine 2 or 3 of them
+in a single window. overlay with evas objects or elm widgets for hud etc. all
+for free. this also implies the engine has to integrate to the efl mainloop
+etc. of course.

+        The most important function of the engine is the createDevice()
+        function. The IrrlichtDevice is created by it, which is the root
+        object for doing anything with the engine. createDevice() has 7
+        parameters:
+
+        - deviceType: Type of the device. This can currently be the Null-device,
+           one of the two software renderers, D3D8, D3D9, or OpenGL. In this
+           example we use EDT_SOFTWARE, but to try out, you might want to
+           change it to EDT_BURNINGSVIDEO, EDT_NULL, EDT_DIRECT3D8,
+           EDT_DIRECT3D9, or EDT_OPENGL.
+
+        - windowSize: Size of the Window or screen in FullScreenMode to be
+           created. In this example we use 640x480.
+
+        - bits: Amount of color bits per pixel. This should be 16 or 32. The
+           parameter is often ignored when running in windowed mode.
+
+        - fullscreen: Specifies if we want the device to run in fullscreen mode
+           or not.
+
+        - stencilbuffer: Specifies if we want to use the stencil buffer (for
+           drawing shadows).
+
+        - vsync: Specifies if we want to have vsync enabled, this is only useful
+           in fullscreen mode.
+
+        - eventReceiver: An object to receive events. We do not want to use this
+           parameter here, and set it to 0.
+
+        Always check the return value to cope with unsupported drivers,
+        dimensions, etc.
