Tests: Util NEWTGLContext: Utilize common createWindow(..) function, switch on-/offscreen via capabilities (Fixes TestTextRendererNEWTBugXXXX)

TestTextRendererNEWTBugXXXX used NEWTGLContext.createOffscreenWindow(..) which created an pbuffer based offscreen
not capable of ES2 rendering etc.

Offscreen tests use NEWTGLContext.createWindow(..) w/ caps.setOnscreen(false),
hence favor FBO instances.
