* Use correct HALF_FLOAT constant for GLES
* Support GLTracer and GL debug in Android
* Support instancing in GLTracer
* Don't use unsupported TEXTURE_{BASE,MAX}_LEVEL in GLES
* Support ABGR8 using swizzle extension
* Move glFramebufferTextureLayer to GLFbo
* Avoid RGB111110F in filters unless its actually supported
* Use the same depth format in all places in FPP
* Print the object with the problem in NativeObjectManager
* JMException does not exist on Android
* Separate GLFbo and GLExt implementations. GLFbo can now be implemented either via vanilla OpenGL3 calls or GL_EXT_framebuffer_*** extensions (OpenGL2.1- only).
* Use modern way of getting supported extensions in core profile.
* Luminance and Alpha formats are not available when running in core profile.
* Bind a dummy vertex array object (VAO) when running in core profile.
* Point sprite mode is always enabled. Since both OpenGL ES 2.0 and OpenGL 3.2 core require it, jME3 is no longer capable of rendering regular points.
Also changed JmeAndroidSystem to store the view instead of the activity.
When users call JmeSystem.showSoftKeyboard(true), the default Android soft keyboard is displayed and any key presses are sent to jME as touch events. Key events are also generated so the user can use the same key listeners as Desktop to keep the user code common between Desktop and Android platforms.
