2016-02-25opengl: shader based polyline rendering - fixes tdf#97137 for OGLTomaž Vajngerl
Adds native opengl polyline rendering to draw polylines, line joins and line caps as triangle strips. The vertex shader allows for the dynamic line width by calculating the correct vertex posiitons, and the fragment shader is used for anti-aliasing.

2016-02-22tdf#82577: Remove prex.h and postx.h wrapper headersJorenz Paragas
Include the X11 headers directly in files that used to include those wrappers, and add the Pixel typedef to files that use it. prex.h included headers that a file including prex.h might not need at all, so when replacing prex.h and postx.h includes, try including only X11 headers that are actually needed in their place. Also fix saldisp.hxx and i18n_xkb.cxx relying on indirectly included X11 headers.

2016-01-06vcl: opengl - Kill the last glErrors on common paths.Michael Meeks
Re-work the makeSomeOpenGLContextCurrent logic into a shared function with the existing AcquireContext logic in the SalOpenGLGraphics impl. Use an OpenGLVCLContextZone placeholder to do both context and zone management - to include destructors into the zone. Fix a number of error cases around SalBitmaps where we did not have a GL context associated when allocating, and/or freeing textures.. Don't drag a (potentially) slower context around in the OpenGLSalBitmap when we're going to check / fetch a better VCL context anyway.

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.
