When m_blitProgram is created the constructor will add it to
QOpenGLContext as a child of that QObject, so it will be deleted
when that QOpenGLContext is deleted as QObject will delete its
children in destructor. Delete it here will cause crash in
thread termination.

total number of lines in the license header.

ES 1.0 didn't have glTexParameteri, which is why we sometimes used
glTexParameterf. However, we shouldn't use glTexParameterf because
that's treating integer values as floating point, which is not type

about supporting ES 1.0 in any case in Qt 5.
