[GLX|WGL]_EXT_swap_control_tear extensions support
asynchronous buffer swaps, i.e. adaptive Vsync.
<https://www.opengl.org/wiki/SwapInterval_aka_vsync#Adaptive_Vsync>
<https://www.opengl.org/registry/specs/EXT/wgl_swap_control_tear.txt>
<https://www.opengl.org/registry/specs/EXT/glx_swap_control_tear.txt>
<http://keithp.com/blogs/async_flip/>
The extensions utilizes a negative interval value,
enabling late swaps to occur without synchronization to the video frame.
Hence '-1' has new semantics, previously it was the 'default value'
of 'untouched vsync interval'.
New default is:
- 0 for unrealized context
- 1 for realized context
+++
It requires [GLX|WGL]_EXT_swap_control,
hence we shall ensure to use use this extension
in the implementation of GLContext.setSwapInterval(..).
+++
Mesa3D seems to support GLX_SGI_swap_control only.
+++
Implemented on Windows and X11.
+++
On GNU/Linux using NVidia driver w/ my setup(*), sadly the query
GLX.glXQueryDrawable(displayHandle, drawable.getHandle(), GLX.GLX_LATE_SWAPS_TEAR_EXT, val);
always returns zero here, indicating async vsync is not supported.
(Queried the attribute for every frame in windowed or fullscreen mode)

(Fullscreen on Bottom not working though)
- Terminology
- ALWAYSONBOTTOM -> isOnBottom
- ALWAYSONTOP -> isOnTop
- Better support for 'isOnBottom' on Windows
- Refine 'SetWindowPos(..)' calls to handle isOn[Top|Bottom]
- Refine 'ShowWindow(..)' calls to handle isOnBottom
- Intercept WM_WINDOWPOSCHANGING to enforce isOn[Top|Bottom],
i.e. change params (hwndInsertAfter and flags).
- Fullscreen on Bottom not working
- While we change all flags appropriately (NOACTIVATE, ..)
and don't issue CDS_FULLSCREEN is on bottom,
Windows seems to enforce the window to be on top
if it is sized to the screen maximum.

Mapped: _tcsncpy_s -> strncpy_s (!UNICODE).
On WinXP MSVCRT has no strncpy_s.

- STATE_BIT_FULLSCREEN_SPAN is private and used for reconfigure,
hence STATE_BIT_COUNT_RECONFIG is needed.
- STATE_BIT_FULLSCREEN_SPAN is added at the end of public state bits
- PSTATE_BIT_MINMAXSIZE_SET is unused.

- to avoid resizing when toggling resizable (change of window border)
we maintain 'RECT insets' in our WindowUserData struct
and fix the client -> top position late in NewtWindow_setVisiblePosSize(..)
after any style change.

WindowImpl
- remove updateMinMaxSize(..) - unused info
- fix appendStateToString: show all maximized state changes if reconfig
- add sizePosMaxInsetsChanged(..) and sendMouseEventRequestFocus(..)
accumulating multiple callbacks from impl.
- add: maximizedChanged(..) notification from native impl.
- refine manual maximized mode
used for OSX and Windows (single extent)
- reconfigMaximizedManual(..)
- resetMaximizedManual(..)
X11 WindowDriver:
- Update maximized at xreconfig, read from _NET_WM_STATE
- Use less Java callbacks from JNI
Windows WindowDriver:
- Use native maximized, if HORZ && VERT,
otherwise use manual maximized for single extent.
- Invisible of top-window -> MINIMIZED/ICONIFY
showing the app in task-bar.

rely solely on insetsChanged(..) (event driven)
Only affected WindowDriver is AWT, which now updates the insets when setVisible(true).
|

If not waiting for resize on main-thread,
corruption may happen at continued rendering.
This has been experienced w/ maximize-horizontally (Bug 1188).

Bug 1178 cc10: We no longer throw an ExceptionInInitializerError
when X11 is not available.
Fix 1178 cc10: We need to use an X11 resource in the constructor
in order to throw an ExceptionInInitializerError if X11 is not available.
We can resolve this by query for the X11 display and screen inside the constructor.

child windows / Fix [Un}Resizable style
- Fix regression on OSX setVisible: in-visibility never reached on child windows
- Fix 'typo' while porting to bit-mask, i.e. '!=' -> '=='.
- Fix [Un}Resizable style
- Use NSResizableWindowMask only for !Undecorated and if STATE_MASK_RESIZABLE is set.

child windows
It has been experienced that UnmapNotify is not sent for child windows when using IconicState!
Hence the visible:=false event never reaches the Window, causing an error.
This patch only uses IconicState for top-level windows and if requested.

alwaysOnBottom and sticky/all-desktop (Part 1)
Change also implements Bug 1186: 'NEWT Window: Use a Bitfield holding all state flags and expose it accordingly',
since it is essential for an efficient implementation.
Part 1:
- Bug 1186
- Using Bitfield, holding public (Window) and private state bits/mask
- Bug 1188
- Window adds:
- [is|set]AlwaysOnBottom(..),
- [is|set]Resizable(..),
- [is|set]Sticky(..),
- [is|set]Maximized(..),
- isChildWindow(),
- Full implementation for X11
- TODO: Implement for OSX and Windows
- Manual tests:
- TestGearsES2NEWT, TestGearsES2NEWTSimple and TestGearsES2NewtCanvasAWT
utilize new NewtDemoListener, which has a key-listener to perform
all [new] actions. See source code of NewtDemoListener.

to return 'int[]'
Certain native RandR13 functions shall return 'int[]',
but will bail out early in case of an error or lack of resources.
The latter is true for getMonitorDeviceIds(..)
where 'XRRScreenResources->ncrtc <= 0', causing return value NULL.
This patch handles the NULL return values,
however, the root cause of having 'XRRScreenResources->ncrtc <= 0'
_occasionally_ lies within the Raspi X11 driver I am afraid?!

Rename window -> underlayWindow.
Fix indentation, long lines & whitespace.
Bug 1178 cc4: another window overlaps NEWT underlay window -> overlay window is still on top.
Fix 1178 cc4: we can request the NEWT underlay window to use always on top.
Bug 1178 cc6: if you render the overlay window transparent -> caps.setBackgroundOpaque(false);
then you will see that the underlay tracker window newer repaints -> looks a bit like a mess.
Attempted fix 1178 cc6: x11 underlay tracker window can be set transparent as well.
FIXME: The underlay tracker window is still filled with opaque garbage.

driver/x11/X11UnderlayTracker
Using NEWT to initialize an X11 window for use by Raspberry Pi users
to handle mouse and keyboard input when using the bcm.vc.iv driver inside xorg.
newt/driver/bcm/vc/iv/WindowDriver
Try use X11UnderlayTracker as input for bcm.vc.iv
If X11 fail to initialize then
track using the /dev/event files directly
using the LinuxMouseTracker.
Input source is switched inside bcm/vc/iv/WindowDriver
by using the new
newt/driver/KeyTracker
newt/driver/MouseTracker
interfaces.

AWT-EDT on Java >= 1.8.0_45
Root cause:
- AWT Toolkit global Lock
Our locking scheme (AWT-EDT-1):
- Surface Lock
- sun.awt.SunToolkit.awtLock()
- Component.getGraphicsConfiguration() -> synchronized(Component.getTreeLock())
Other AWT-EDT-2 by Webstart:
- synchronized(Component.getTreeLock())
- sun.awt.SunToolkit.awtLock()
Results in a deadlock.
Solution:
- Issue Component.getGraphicsConfiguration() before awtLock(),
where Component.getGraphicsConfiguration() is being used to
detect possible reconfiguration.
- Also use updated AWTGraphicsConfiguration's GraphicsConfiguration
if no 'new' detection is required.

when reconfigured.
JOGL AWT Components, e.g. GLCanvas or NewtCanvasAWT,
may be reconfigured by moving them to another display/monitor
or by other means.
Since AWT has no means to notify the user code via an event,
JOGL components usually determine the reconfiguration via
the override 'GraphicsConfiguration getGraphicsConfiguration()'.
GLCanvas is sensible to this reconfiguration,
however its AWTGraphicsConfiguration (owned via JAWTWindow)
is not changed.
Implement reconfiguration detection for all JOGL AWT Components
and update the AWTGraphicsConfiguration if required.
For now, constraint reconfiguration on GraphicsDevice change
as currently implemented in GLCanvas.
The updated AWTGraphicsConfiguration allows using the updated
GraphicsDevice as it might be required for further information,
e.g. pixel-scale on OSX.

creation
- Refines commit a566a1b5a2828b38f1a5c4dfb215ab9b03e7acaa
- Issue clamping at 'canCreateNativeImpl()' instead of 'createNativeImpl()',
allowing to define clamped position and size before utilizing these values
at caller 'createNative()'.
Otherwise a clamped position would cause to wait for the original position
after 'createNativeImpl()'.
This also allows to remove the positionChanged(..) / sizeChanged(..) calls in
the native CreateWindow0() implementation.
