SoftFever d8369e5f75 Fix faint toolbar icons on Wayland (#13723) ...

Use glBlendFuncSeparate in GLTexture::render_sub_texture so destination
  alpha stays at 1.0. The Wayland compositor honors framebuffer alpha for     window compositing; the previous straight-alpha blend reduced dst alpha
  at anti-aliased icon edges, making them semi-transparent against the
  desktop. RGB blending is unchanged, so X11/Windows/macOS are unaffected.
