This commit performs two main changes: * Alters the shaders to use only strictly conformant GLSL 2.0. * Alters the Windows UI to use ANGLE via GL ES 2.0 and EGL 1.4. This commit also drops official support for Windows XP, since ANGLE requires a non-XP toolset to build. It is still possible to build SolveSpace for Windows XP using: cmake -T v120_xp -DOPENGL=1
