In some configurations (esp. with ATI card, latest drivers, WinXP), creation of
dummy GL context fails when system tries to swap buffers on newly created dummy
To fix this, I suggest to disable autoRedraws and automatic swapBuffers for
dummy context, because of it is not needed as far as dummy context is only used
to get extension strings and function pointers.
Proposed change is to add disabling code for these modes just after setting
zero size of GLCanvas in WindowsGLContextFactory.getDummyGLContext(...):
This change is proven to fix described wrong behavior and additionally provides
(really minor) improvement for app startup time (esp. if VSync is enabled).
