Moved shaders to resource folder.  Use PNGs instead of DDS in sample.
Added some geometry functions from WorldWindJava
Added Animator TypeEvaluators for Angle,Position, and Double
Added DEBUG option which will glGetError after each GL call
Bulk functionality port from java WorldWind and ETC1 compression support

-Orbit view limits & collision detection ported
-Basic View near clip relative to view distance
-Basic view modelview matrix clamped to ground
-ETC1 Compression support.
	-Loading compressed pkm with alpha channel
	-TiledImageLayer <TextureFormat> configuration
	-Loading compressed imagery data
	-Loading uncompressed data to compressed format
	-Compressing image tiles during download
-GpuTextureData multi-texture support
-Perframe statistics ported
-Diagnostic rendering (Extents, tile ids)
-WorldWindowGLTexture view (based on TextureView instead of SurfaceView)
-PickFrustrum support
-PickSupport class includes binding of texture based FrameBuffer instead of default FrameBuffer
-CompassLayer uses ETC1 compressed image w/alpha channel
-BasicInputHandler uses standard GestureDetector for single-tap gestures
-Maven project configuration
Ported more geometry for raycasting.  View.getEyePosition removed Globe argument
Ported PositionListener & SelectListener
Terrain surface intersection
Extracted WorldWindowImpl from WorldWindowGLTextureView functionality and clocked FrameRate.

-setFrameRate(0) will use only render upon request.
-EarthMap layer uses ETC1 compressed pkm image.
-Added statusBar drawables
Organize shaders by functionality instead of seperate shaders for each layer.  Add layer opacity support
Added support for loading texture mipmaps from filesystem
Added alpha channel support to ETC1Compressor
Vertical exageration refresh added terrain tiles
Seperated PickSupport begin/end with framebuffer binding
Added SurfaceShape support and SurfaceQuad implementation.

-Prerenderable support added as infrastructure.
-RenderTarget support
-SurfaceObject/SurfaceShape infrastructure. i.e. AbstractSurfaceObject, AbstractSurfaceShape
-SurfaceQuad outline implemented.  Interior polygon tessalation not yet implemented.
