- Add 0001-Allow-compilation-on-GLES-platforms.patch
  The QOpenGLFunctions_3_2_Core class providing the framebuffer
  blit functions is not available on GLES 2 builds of Qt5. Let Qt
  handle the framebuffer blit, and just use the GLES/GL subset
  provided by QOpenGLFunctions for the remainder.
  Fix for https://gitlab.kitware.com/vtk/vtk/issues/17113

Subject: [PATCH] Allow compilation on GLES platforms
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
On GLES 2.0 platforms (more specifically, for Qt5 "opengl es2" builds),
QOpenGLFunctions_3_2_Core does not exist. Since Qt 5.7,
QOpenGlFramebufferObject has a static wrapper method for framebuffer
blitting, which in worst case is a noop.
