Subject: [PATCH] Allow compilation on GLES platforms
|

MIME-Version: 1.0

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.
