Certain scenes crash on Android (and anything with GLES)

    Description

      effectgallery crashes atm on an NVIDIA Shield TV (Tegra X1, Android 7.0)

      But even the new SampleProject was shown to crash both on a Mali and an NVIDIA based Android device. (these have GLES 3.1 and 3.2, respectively)

      This is due to a QOpenGLTexture issue:

      ********** Crash dump: **********
Build fingerprint: 'NVIDIA/foster_e_hdd/foster:7.0/NRD90M/2427173_1038.2788:user/release-keys'
pid: 20017, tid: 20060, name: Qt3DRender::Ren  >>> org.qtproject.example.q3dsviewer <<<
signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x0
Stack frame #00 pc 0000000000000000  <unknown>
Stack frame #01 pc 0000000000449cec  /data/app/org.qtproject.example.q3dsviewer-2/lib/arm64/libQt5Gui.so: Routine QOpenGLTextureHelper::glTexStorage2DMultisample(unsigned int, int, unsigned int, int, int, unsigned char) at /home/agocs/av/qtbase/src/gui/opengl/qopengltexturehelper_p.h:609

      When that is fixed, the crash is eliminated but the output is incorrect since Qt 3D fails in BlitFramebuffer due to attempting to use a function (glDrawBuffer) that is not present in OpenGL ES.

      And when that's fixed, it fails due to QT3DS-1756.
