Changes

TestNewtKeyEventAutoRepeatAWT: Wait for 'some' KeyEvents and check count; TestNewtKeyPressReleaseUnmaskRepeatAWT: Enable NewtCanvasAWT test

GLRendererQuirks.RequiresBoundVAO: Removed, it _is_ in the GL 3.2 core spec - Setting up default VAO for all GL >= 3.2 core ctx.

Refines commit 9b6448b1d54716fd455c0cad0c6133c0edeb3bb8

Due to GL 3.2 core spec: E.2. DEPRECATED AND REMOVED FEATURES (p 331)
"There is no more default VAO buffer 0 bound, hence generating and binding one
to avoid INVALID_OPERATION at VertexAttribPointer."

More clear is GL 4.3 core spec: 10.4 (p 307):

"An INVALID_OPERATION error is generated by any commands which
modify, draw from, or query vertex array state when no vertex array is bound.
This occurs in the initial GL state, and may occur as a result of BindVertexAr-
ray or a side effect of DeleteVertexArrays."

I just have read (same spec) 2.10 (p 46/47):

"An INVALID_OPERATION error is generated if any of the *Pointer commands
specifying the location and organization of vertex array data are called while zero
is bound to the ARRAY_BUFFER buffer object binding point, and the pointer argu-
ment is not NULL."

.. which only constraints the *Pointer command use to _VBO_, not forcing a VAO.

EGL/EGLExt Robustness: Use NIODirectOnly for all bindings. For these internal APIs, critical array is not required, hence redundant.

GLX/GLXExt Robustness: Use NIODirectOnly for all bindings. For these internal APIs, critical array is not required, hence redundant.

CGL/CGLExt Robustness: Use NIODirectOnly for all bindings. For these internal APIs, critical array is not required, hence redundant.

WGL/WGLExt Robustness: Use NIODirectOnly for all bindings. For these internal APIs, critical array is not required, hence redundant.

NEWT/OSX getLocationOnScreenImpl(..): Use real OSXUtil.GetLocationOnScreen(..) if onscreen and surface available.

Fix AWTRobotUtil.keyType(..): 'c0' start count must be outside of retry loop; also wait a few ms after key action

TestNewtKey*: Don't test TAB (focus traversal, duh!); Add AWTRobotUtil.requestFocus(robot, ..) for kbd input on Windows (some 'confusion' w/ prev unit test runs)

NEWT Windows: Add more verbose DEBUG information for FOCUS handling

Fix regression of commit e5692f615a8c40e7ca750261baf5e8ecdb0a34b8: CGL/CGLExt Robustness ..

Fix NEWT KeyEvent: Deliver keyChar w/ pressed and released; Deliver proper modified flags and modifier-key events; Simplify Windows key handling

Preface: Modifier-keys are SHIFT, CTRL, ALT and META and they have a matching modifier-bit.

- Simplify Windows key handling
  - Employ MapVirtualKey(..) for virtual-key to character and scancode to virtual-key mappings,
    allowing to drop tracking of keyCode to keyChar in java code.

    This also removes the platform restriction of delivering keyChar at TYPED only.

- Deliver keyChar w/ pressed and released
  - Due to the lift restriction on the Windows platform (see above),
    we can deliver keyChar w/ all key events on all platforms.

- Deliver proper modified flags and modifier-key events
  All modifier-keys deliver pressed, released and typed events
  with their modifier-bit set.

The above is covered by unit tests, which passed on X11, Windows and OSX (manual test run).

ShaderProgram: Program name is valid if non zero; Add init(GL) return value for success.

TestInitConcurrent02NEWT: Disabled for auto unit test until further analysis - Windows/ATI driver crash

Shader: Add '#define texture2D texture' for GLSL >= 130 ; TestGearsES2AWT add forceGL3; TextureDraw01ES2Listener uses defaultShaderCustomization()

Add OSX CALayer OpenGL 3 (core) support: Derive pixelformat from parent (GL3), use GL3.2 compatible shader; Use VBO in general.
