# This file is passed to the linker. It defines that
# only functions which start with prefix "Psych", e.g.,
# PsychDrawText, PsychMeasureText, ... have global
# scope in the process which loads the ptbdrawtext_ftgl.so
# DrawText text rendering plugin.
#
# All other functions only have local scope - they are
# invisible to the hosting process.
#
# We add this to avoid polluting the host process with
# definitions of our own QT-Toolkit "lookalike" implementations
# of a few internally used QT classes. Our lookalikes are
# very thin emulations of the real QT classes, stripped to
# the bare essentials needed for the OGLFT code to by happy.
# They are incomplete, but API compatible bits, which are
# entirely ABI incompatible.
#
# This is important because Octave's native GUI uses the QT
# toolkit for its GUI code and we want to avoid any kind of
# possible interference between our plugin and the QT-GUI.
