Set JAWTWindow:reqPixelScale before the DPI scaling factor is determined, so if GLCanvas.setSurfaceScale() has been called, the correct 'reqPixelScale' is available. It's possible to call GLCanvas.setSurfaceScale() before JAWTWindow has been created. Fix feature AUTOMAX_PIXELSCALE so the requested pixel scale is used.

I discovered the NASA WorldWind was setting reqPixelScale immediately after GLCanvas was created. The code in JAWTWindows ignored 'reqPixelScale' when setting up the 'hasPixelScale' value. I surmise that AUTOMAX_PIXELSCALE was intended to all a user to set the surface scale with the GLCanvas.setSurfaceScale() call, which sets 'reqPixelScale' These changes allow the override of using 'maxPixelScale' to set 'hasPixelScale'.

The call to GLCanvas.createJAWTDrawableAndContext() is made when the first GLCanvas.addNotify() call is made. The JAWTWindow is created, and JAWTWindow.lockSurface() causes the DPI scaling value to be determined in JAWTWindow.updatePixelScale().

… coordinate values instead of the AWT screen coordinates. Added Windows JOGL jar files that include sgothel/jogl#110 and sgothel/jogl#112.  Noticed that some null pointer exceptions occurred during KMLViewer startup; added null pointer checks.

Needs more work. The drawable surface isn't the entire frame enclosing the GLCanvas.

* Fixes for DPI scaling.  Mouse and select events now deliver GL surface coordinate values instead of the AWT screen coordinates.  Added Windows JOGL jar files that include sgothel/jogl#110 and sgothel/jogl#112.  Noticed that some null pointer exceptions occurred during KMLViewer startup; added null pointer checks.

* Update for gluegen 9301bf1854 May 15 07:08:20 2023, jogl 900c35c6a4 May 15 06:47:22 2023

* Use DPI scaling to scale fonts rendered in the GLCanvas.

* Update with gluegen/jogl code from 6/17/2023, gluegen commit 42bd110d9e, jogl commit 900c35c6a.  Includes fix for jogl version of TextRenderer.  Added Linux native jar files.
