* Tighter BOINC graphics app compliance
* Idependent of debug/release mode

* Arguments need to be passed in degrees not radians
* Conversion is done right after shared memory parsing (we only need degrees anyway)

* It was caused by the search marker not being updated after resize
* Note: we do *not* update the marker each frame, we just render it to avoid overhead
* We now reset the update flag on resize (guess what, it works)

* Should again be related to OpenGL context reset
* Explicitly deleting and regenerating the GL lists might solve it
* Minor reindentation and line break improvements
* Makefile improvement (just clean known object files)

* The fonts also have to be reinitialized as they rely on the OpenGL context being "reset" by windoze
* Introduced a few sanity checks for resource handling
* Moved initial fullscreen toggle (release mode) to be called after initialize() as now there's a dependency when on windoze :-/

TODO: X11 doesn't need the recycling procedure
* It should only be done for windoze to avoid extra overhead
* How to determine the OS? Does SDL offer something reliable?

* Reinitialize OpenGL context fullscreen toggle
* Extended a few comments

* Windoze "resets" the OpenGL context when SetVideoMode is called - ergo, we need to reinitialize the context
* Added a switch (recycle) to initialize() to distinguish between one-off and recurring actions

* The interface declared in AbstractGraphicsEngine is now implemented in the most specialized class only (to make sure it's called, down the inheritance hierarchy)
* The abstract or generelized classes (up the hierarchy) got local implementation (protected) which are called by their respective children.
* Fixed a bug in the old starsphere code. Search marker rendering deleted to much (memory corruption)! Does OpenGL do any boundary checking?

* Using single font instances per text group (adds flexibility, avoid font change during render)
* initialize() and resize() are now virtual, and overridden in subclass
* HUD dimensions now follow actual size (no more scaling needed)
* No more FSAA needed
* Removed unnecessary Open GL calls during render

Pro:
- Crystal clear HUD text
- Constant HUD text size
Con:
- Slightly higher CPU usage (5% -> 7.5%, also for full screen?)

* To include new classes
* To use a "normally" installed OGLFT

* Proper use of enum types
* Current values of ascension/declination properly initialized (have to get a value outside the valid range)

* Support for flexible requests of engine and specific science app support
* Could easily be passed as command line parameter for instance

* Now there's a generic Einstein@Home and a science run specific part
* Search information retieval and rendering moved into subclass
* Renamed a few things as they're now true members
* Moved a few things from private to protected (obviously)

* Now there's a generic and science application specific (e.g. shared memory handling) part
* The actual shared memory indentifier now has to be passed during initialize() instead of being hard-coded
* All this might eventually allow us to incorporate some portions of this API into something more general like a generic graphics toolkit

* Grayscale faces do need a backgorund color
* Texture faces do need enabled textures (oh well)
* Translucent faces need activated alpha blending (you guessed it)

Added preliminary test code for OGLFT which might eventually replace FTGL (so far FTGL seems to be the culprit that causes the nasty "HUD killing" bug)
