Description Sven Gothel 2013-04-17 12:49:00 CEST 
[a] WindowsBitmapWGLDrawable's BITMAPINFOHEADER's BiBitCount, as well as 
[b] WindowsWGLGraphicsConfiguration choosing needs to be refined.

Better: Constrained to RGB555 and RGB888, w/ alpha optional.

Otherwise either WindowsBitmapWGLDrawable's GDI.CreateDIBSection fails [a]
or SetPixelFormat(..) fails [b].
Comment 1 Sven Gothel 2013-04-18 02:36:21 CEST 
Refine Unit Tests ; UITestCase.Snapshot: Add RGBA bits to filename.

 -  Split TestGLAutoDrawableFactoryOffscrnCapsNEWT to
       TestGLAutoDrawableFactoryGL2OffscrnCapsNEWT and
       TestGLAutoDrawableFactoryES2OffscrnCapsNEWT
 -  TestGLAutoDrawableFactoryGL2OffscrnCapsNEWT contains more 'Bitmap' tests of 
     various caps, w/ snapshots.                                                                                                            

Filter invalid PFD configs

 - Filter invalid PFD configs
   - WindowsBitmapWGLDrawable: Clip chosenCaps to RGBA888[0|8]
   - WindowsBitmapWGLDrawable: Only use BITMAPINFOHEADER.BiBitCount=24
   - WindowsWGLGraphicsConfiguration: Only allow GDI BITMAP PFD's w/ RGB888 w/ 
      alpha <= red, others may fail
    
 - WindowsWGLGraphicsConfigurationFactory.getAvailableGLCapabilities()
   - Fetch ARB caps w/o BITMAP
   - Concat GDI [BITMAP] caps
Comment 2 Sven Gothel 2013-04-18 09:08:26 CEST 
Further restriction of Windows BITMAP PFD's - RGB888 and !alpha only

On Windows Vista machines, using alpha, i.e. RGB8888 failed to SetPixelFormat(..),
hence only allow RGB888.

Exclude updateGraphicsConfigurationARB(..) usage for 
BITMAP (Windows Vista does report BITMAP w/ ARB PFD).

On Windows Vista machines, ARB PFD selection reports BITMAP which is attempted to be used.
Excluse updateGraphicsConfigurationARB(..) from BITMAP query, similar to getAvailableGLCapabilitiesARB()
from commit 61a47e07975eb2fd8b1f5f60552935c993a6eef6.

WindowsBitmapWGLDrawable: Requires GLProfile.GL2, fix BITMAP GLCaps ASAP at Ctor instead of setRealized(true); WindowsWGLContext: Exclude ARB creation for BITMAP

Unit Test TestGLAutoDrawableFactoryGLnBitmapCapsNEWT added using BITMAP on GLProfile.getDefault()

https://jogamp.org/chuck/job/jogl/971/ shows good results on Vista and Win7
