Changes

GLContext*'s ctxGLSLVersion: Use zeroVersion to denominate uninitialized VersionNumber instead of null, it's get*string returns a zero length string instead of null.

Move JPEGDecoder.PixelStorage -> TextureData.ColorSink: Appropriate name + public use

Complete commit e7064ece049705e013d80985eae698ce0ee3c4e3: Add getDefaultPixelDataFormat(), complementing getDefaultPixelDataType()

Add missing JogAmp (c) note - using date of 1st JogAmp edit.

TextureData: Add PixelAttributes and PixelBufferProvider; ColorSink back to JPEGDecode (not general enough)

- TextureData: Add PixelAttributes and PixelBufferProvider
  - PixelBufferProvider is intended as a pattern allowing
    producers (i.e. GLReadBufferUtil) to utilize custom pixel buffer
    for various intend.

  - PixelAttributes can be chosen by PixelBufferProvider implementation
    and groups the texture's pixel/data format and type.
    TextureData uses PixelAttributes internally now.

- ColorSink back to JPEGDecode (not general enough)
  - Partially reverts 94ea306d1809290db678d3181619bdc39d4334bb

GLReadBufferUtil: Utilizing PixelBufferProvider; Adding AWTGLReadBufferUtil adding BufferedImage support; Demonstrating w/ unit tests.

Fix Bug 600 and Bug 721: Adding support for multiple monitors w/ NEWT

- Support for all monitor devices and their available modes
  - X11: Use RandR 1.3 if available
  - Retrieve information
  - Changing a monitor device's mode

- Support for dedicated and spannig fullscreen
  - See <http://jogamp.org/files/screenshots/newt-mmonitor/html/>

- TODO:
  - X11 RandR does _not_ relayout the virtual screen size
    and neither the CRT's viewport.
    We may need to relayout them if they were covering a seamless region
    to achieve same experience!

  - OSX: No machine to attach a secondary CRT -> TEST!

- Tested Manually for Regressions
  - Linux ARMv6hf (Rasp-Pi/BCM, Panda/X11)
  - Android (Huawei, Kindle)

- Tested Manually and junit:
  - X11/Linux
    - NV, ATI-Catalyst w/ 2 CRTs
    - VBox w/ 4 CRTs

  - Win/Windows
    - NV, w/ 2 CRTs
    - VBox w/ 4 CRTs

  - X11/OpenIndiana, NV, 1 CRT

Fix GLSL Version Exposure: Type in 'static' GL -> GLSL matching, don't set GLSL version if GLSL is n/a

Fix GLX: X11GLXContext used wrong FBConfig n/a query; X11GLX*: If FBConfig is n/a force GLX (server) version down to 1.1 to avoid crashes w/ old GLX server (i.e. Mesa 4.*).
