Android: Bump version.code: 914010

Fix regression of commit de2b129a56335262a44a05541a3ab2e35668cc6e: ProjectFloat Matrix Multiplication of gluUnProject(..) impl.

ProjectFloat's previous gluMultMatricesf(..) used row-major order,
but the replacement multMatrixf(..) uses column-major order (like OpenGL, ..).

Note: The replaced 'gluMultMatrixVecf' by multMatrixVecf() already
      used column-major order.

Fix: Reverse the arguments of matrix multiplication
    m1 x m2 -> m2 x m1

Added proper API documentation in FloatUtil -> Column Major Order of Linear Matrix Layout

Add unit tests for gluUnProject fix (commit cbc77718f01a8190e1a8aa0e9afdc2a3a3403358)

GLContext/Surface Deadlock: Add unit test, provoking deadlock w/ 2 threads, one holding the surfaceLock acquiring ctxLock where ctx acquires the surfaceLock

GLContext*: Remove '[set/is]Synchronized(..)' - Defaults to wait for locks: 1. Drawable, 2. GLContext

Remove deadlock situation where thread-1 (Animator Thread) holds the GLContext-Lock
and acquires the Surface-Lock, while thread-2 (UI/Main/EDT) holds the Surface-Lock
and attempts to create the GLContext and hence acquires the GLContext-Lock.

A GLContext-Lock and hence makeing the GLContext current requires to hold
the Surface-Lock. The prev. code acquired the locks in reverse order and
allowed the deadlock as described above.

This fix acquires the locks in the proper natural order
  1 - Surface-Lock
  2 - GLContext-Lock

This fix also renders the use of the non-synchronized behavior invalid,
since it is bogus not to wait for the GLContext lock where it waits for the
Surface lock. It also seems nonsense not to wait for any of both locks
and our code always waited for both (synchronized := true).

The GLContext [set/is]Synchronized(..) methods are removed
and waiting for the lock per default is the correct behavior.

Demo/Test GearsES2: Supress reshape debug println

TestGLContextSurfaceLockNEWT: Add GLWindow destroy @ test end

Refine commit be7cac1713b166ca6578c685ec8a7231a8429919:

Throw ClassNotFoundException in Display/Screen/Window factory if neither custom
nor default class is available.

Suppress Warning of non existing custom class (in non DEBUG mode),
rely on later ClassNotFoundException (see above).

Fix Bug 572: AWT-GLCanvas shall force setRealized(true) on AWT-EDT avoiding AWTTree deadlock

GLContext.destroy() error case: Lock hold > 1 - More explicit error message.

Graph/Glyph: Clarify public Font.Glyph and private FontInt.GlyphInt

graph/font: Add "public float getAdvanceWidth(int i, float pixelSize);"

Font::getAdvancedWidth(..) allows applications to query a glyphs width
with a given pixel size, as it is being used for rendering.

GPUTextRendererListenerBase01: Remove unused var.

Clarify API Doc: GLRunnable and it's GLAutoDrawable::invoke(..)

Graph/Font Demo: Add simple 'one-file' demo/test 'TestTextRendererNEWT00'

.. also adding missing (c) of other graph unit test.

Java Source Files: dos -> unix format

Unit Test Util NEWTGLContext: Pass GLCapabilities instead of GLProfile, allowing custom pixelformat caps.

Graph/Font Demo: Add simple 'one-file' demo/test 'TestTextRendererNEWT10' w/o GLEventListener
