2015-12-11tdf#93529 - move to a Mac-like double-buffered OpenGL model.Michael Meeks
This moves us to always rendering to an off-screen texture, and then (at idle) blitting this to the screen & swapping buffers. Ideally we should never see any rendering, or flicker again with this approach. Several fixes are included: + avoid multiple OpenGL contexts being created for the same window, created excessive flicker problems. + de-virtualize UseContext - which context we use is less critical. + kill 'mbOffscreen' distinction - all VCL rendering is offscreen. + implement 'doFlush' and high priority idle flushing. + bind stencil buffer for clipping vs. textures - fixing complex clopping when rendering to virtual-devices, and off-screen. + document environment. variables. + use white as default background glClear color, but red or random color for DBGUTIL.

2015-11-17Check for OpenGL errors right where an error might be generatedTor Lillqvist
CHECK_GL_ERROR() is now zero-cost in a production build, so no reason to avoid it. Don't check for OpenGL errors after glX or wgl calls. They don't generate OpenGL errors but use the X and Win32 error mechanisms, as far as I see. Change-Id: I8f97ef434cbdc89d6e345a247456cfc4a1a82bb6
