* Deprecated LTC and LATC texture formats, OpenGL3+ does not support them. Instead RGTC / BC5 must be used.
 * Add missing license to InstancedGeometry.
 * Minor cosmetic / doc changes.
Merge branch 'master' of github.com:jMonkeyEngine/jmonkeyengine
 * ToneMap.frag: Fix warning about gl_FragColor when compiling for GLSL 1.5 and higher
 * Added two missing 32-bit image formats to TestImageRaster: ARGB8 and BGRA8
* When creating display pixel format, do not use withSRGB as it could cause display creation to fail (when gamma correction is enabled). Based on online research, it seems that it is not necessary, and simply enabling SRGB writes on the main framebuffer is enough.
 * Added additional checks when enabling SRGB writes to ensure the default framebuffer actually supports it, and print a warning if it doesn't.
 * Forgot to remove withSRGB from LwjglCanvas
Merge origin/master
SDK: remove duplicate code in AbstractSceneExplorer's constructor
One constructor with the shared logic, other constructor are just sugar
SDK: fix "Add Control" to JmeAssetLinkNode (no more NPE, and correct display and edition)
Merge pull request #144 from davidB/fix_sdk_addControlToLink

Fix sdk add control to link
 * Add new flag to Platform enum which specifies if its 32-bit platform or 64-bit.
 * Add new but currently unused native extraction engine which supports user-specified native libraries as well as deferred extraction of libraries.
 * Ensure the statistics properly represent number of objects / triangles / vertices rendered when using instancing
 * Deprecate texture wrap modes not supported in OpenGL 3
 * Make sure engine is not using them anywhere
 * Put comment markers around imported library contents when loading shader
 * Fix "m_LightPos redefined" shader compile error in PostShadow.vert
* Put the shader compile log on the next line so its slightly more readable
 * Fix two more un-compliant PostShadow shaders
* More javadoc in NativeLibraryLoader
 * Added GL interface generator tool
* Use relative path to find renderer source code for GLAutoGen
