Add a EGL renderer (via ANGLE) for Windows
This is for adding a EGL-based renderer which is done via the ANGLE project, which translate EGL calls to Direct3D 9/11. This is done as a possible solution to issue #105, especially for cases where the needed full GL extensions to map OpenGL to Direct3D is unavailable or unreliable, or when the OpenGL implementation from the graphics drivers are problematic. To enable this, do the following: -Build ANGLE and ensure the ANGLE libEGL.dll and libGLESv2.dll are available. A sufficiently-recent ANGLE is needed for things to work correctly--note that the copy of ANGLE that is included in qtbase-5.10.1 is sufficient. ANGLE is licensed under a BSD 3-clause license. -Build libepoxy on Windows with EGL support enabled. -Currently, prior to running GTK+ programs, the GDK_DEBUG envvar needs to be set with gl-gles as at least one of the flags. Known issues: -Only OpenGL ES 3 is supported, ANGLE's ES 2 does not support the needed extensions, notably GL_OES_vertex_array_object, but its ES 3 support is sufficient. -There is no autodetection or fallback mechanism to enable using EGL/Angle automatically yet. There are no plans to do this in this commit.
