add hand to scene to use instead of mouse pointer soon
move responsibility for the Hand  (create, destroy, add to World) to GodManipulator
Merge remote-tracking branch 'origin/master' into hand_of_god
Merge branch 'enable_zooming' into hand_of_god
add default transform matrix to Hand which does the scaling and rotation to default position
add first linking between mouse position (screen) and Hand position (world).

for now, simple mapping of screen X,Y coordinates to world X,-Z coordinates.
Merge remote-tracking branch 'origin/master' into hand_of_god
grant the GodManipulator access to modelviewprojection matrix
Merge branch 'master' into hand_of_god
remove hand.3DS from elemate repository
change path to hand model. remove unneeded include
setup rendering to texture / flush program #29
fix buffer data size #29
add depth texture buffer #29
add context resize callback #29
fix warning of unreferenced parameter
Merge branch 'particle_vbo_28', because the shape drawables cause program crash

Don't really know where this comes from, but occurs only when rendering to texture. And only with osg's (shape) drawables, created after game start.
This also fixes the problem that (debug) particles where not visible on AMD. Seems that we can't rely on most of the osg drawables when using modern opengl (means after setUseVertexAttributeAliasing(true)).
add resize view warning, as it does not work yet
Merge branch 'render_to_texture_29' into hand_of_god
pass depth buffer to the manipulator. not working yet, as the Texture2D doesn't contain a valid Image
