This is not 100% true. If you create a big window on a big screen and then drag
it to the smaller screen - you'll get a window which is bigger than the screen.
So with your fix in case the GL_MAX_TEXTURE_SIZE/2 < SCREEN_SIZE, wouldn't the
frame automatically constrain itself to the bounds of the smaller screen
when dragged from the bigger screen?
The question is about do we trust to the GL_MAX_TEXTURE_SIZE or not, if
we assume that GL_MAX_TEXTURE_SIZE/2 is a maximum supported opengl
texture size, and it less than a screen-> we could assume that the
screen size is supported only or... what size?
With best regards. Petr.

Hello.
Please review the fix for jdk 8.
Some history of the bug:
- Initially we did not constrain size of the window and got JDK-7160609
- Then we try to use a union of the screens to constrain of the window and got
JDK-8015100.
- Then we start to use GL_MAX_TEXTURE_SIZE/2. But for some systems it was too
big JDK-8023159 OR too small JDK-8027778.
But on macosx 10.9 the windows are constrained automatically by the size of the
screen(Petr please confirm).

GL_MAX_TEXTURE_SIZE/2<=8192), so we should behave like the native application

nativeGetMaxTextureSize was moved under the render lock, where other related
opengl data are initialized(see CGLGraphicsConfig.getCGLConfigInfo()). To me it
seems safe because it works in similar way in jdk7 and CGLGraphicsConfig is
recreated on the each event related to the screen(new resolution, new video
card, etc).
Also I adds updateMinimumSize to the displayChanged and notifyReshape, to
reapply a new constrain to the window.
Any suggestion are welcome.
Bugs which are covered by this fix:
https://bugs.openjdk.java.net/browse/JDK-8027778- after the fix the maximum
size is not less than the screen
https://bugs.openjdk.java.net/browse/JDK-8015100 - we use half of the
GL_MAX_TEXTURE_SIZE if supported by the system, and usually it is larger than
the screen
https://bugs.openjdk.java.net/browse/JDK-8010999 - the maximum possible size of
the window is 8192
