Text Rendering, Bugfixes, Tweaks
#ADD: Added some Duality Logo images as Pixmaps, Textures and Materials.
#ADD: Added SharpMask DrawTechnique and Shaders.
#ADD: Added new SharpBitmap rendering method for Fonts to allow high quality Font rendering with relatively small bitmaps.
#REMOVE: Removed all "ContentPath_Xy" constants from Resource classes, since they're redundant and do nothing but clutter the API.
#CHANGE: Renamed some default content / API improvements.
#CHANGE: Removed Filtering and GlyphRenderHint properties from Font class and replaced them with a new GlyphRenderMode enum property.
#FIX: Fixed Camera zoom when simultaneously dragging the Scene in the CamView.
