Bug 1150 - Fix GLContextImpl.createImpl(..) NoARBCreateContext and '!ARB GL >= 3.1' issues
This fix solves the described issues below. Test cases added for onscreen and offscreen drawables, the latter includes Window's bitmap special case. GLContextImpl.createImpl(..): Fix NoARBCreateContext and '!ARB GL >= 3.1' issues: ================================================================================= GLContextImpl.createImpl(..) implementation of X11GLXContext and WindowsWGLContext wrongly handles the case of NoARBCreateContext. Here the !ARB created context shall allow GL >= 3.1, since ARB context creation is disabled and 'no mix' can occur. The latter was already intended due to failure criteris 'createContextARBTried' in: if( glCaps.getGLProfile().isGL3() && createContextARBTried ) { failure("createImpl ctx !ARB but ARB is used, profile > GL2 requested"); } Further, WindowsWGLContext treats glCaps.isBitmap() within the 'createContextARBTried=true' case, but it shall never tried using the ARB context creation method. This even lead to the issue of creating a 1.1 context, but having the ProcAddressTable being still on the GL > 2 cached table. This is due to 'setGLFunctionAvailability(..)'. Ensure 'setGLFunctionAvailability(..)' is functional ==================================================== Caller shall either throws an exception if method returns false or issues a state reset. In case 'setGLFunctionAvailability(..)' throws an exception itself, the states are no issue.
