Typo in egl_create

[plops]

I think in the function egl_create renderable_type should be surface_type:

        if ((renderable_type & EGL_PBUFFER_BIT) == 0) {
            continue;
        }
        if ((renderable_type & EGL_WINDOW_BIT) == 0) {
            continue;
        }

Otherwise surface_type wouldn't be used at all.

I tried a fix in my fork. There is no change in the program behaviour that I can see.

I also had to link with libEGL and libGLESv3 to prevent a dynamic linker error that prevents the program from starting.
