Hi folks,

I'm trying to use the MolDraw2DCairo class to generate PNG images. But no 
matter what I've tried, including setting the 'noFreetype' param to true in the 
c'tor, I get an empty string from getDrawingText() and an exception with 
message "PNG header not recognized". I traced this problem to the call to 
cairo_surface_write_to_png_stream() in MolDraw2DCairo.cpp, which gives an empty 
string and returns the cairo error/status "no memory." Any ideas what's causing 
this? I know nothing about cairo/freetype... I'm using cairo 1.16.
