D16802: effects: attempt to screenshot on OpenGL ES 2.0 instead of failing

bshah added a comment.


  This is super weird tbh, if I add workaround for Adreno, in blitSupported to make it return true. It crashes when doing screenshot, with following
  
    "No provider of glBlitFramebuffer found.  Requires one of:\n"
    "    Desktop OpenGL 3.0\n"                                   
    "    GL extension \"GL_ARB_framebuffer_object\"\n"           
    "    OpenGL ES 3.0\n"                                        
    "    GL extension \"GL_EXT_framebuffer_blit\"\n"             
    "    GL extension \"GL_NV_framebuffer_blit\"\n"              
  
  But if I just ignore blitSupported in the screenshot effect it doesn't crash.. it is one "WAT" moment.
