  later so it doesn't have this issue:

    Fix FBO restoring in QOpenGLTextureGlyphCache

* but backport to 5.0.2 is using GLuint:
  and causes build failure without -fpermissive:
  | qtbase/5.0.2-r3/qtbase-opensource-src-5.0.2/src/gui/opengl/qopengltextureglyphcache.cpp:151:51: error: invalid conversion from 'GLuint* {aka unsigned int*}' to 'GLint* {aka int*}' [-fpermissive]
  |      glGetIntegerv(GL_FRAMEBUFFER_BINDING, &saveFbo);
  |                                                    ^
  | /usr/include/GLES2/gl2.h:536:37: error:   initializing argument 2 of 'void glGetIntegerv(GLenum, GLint*)' [-fpermissive]

  |                                      ^

* resync with version from 5.1.1 to fix this
