AthensSurfaceExamples does not work - FFIUnsupportetUntypedLiteral

[astares]

In Pharo 13 run

• AthensSurfaceExamples class>>#draw2Strings
• AthensSurfaceExamples class>>#drawFontMetrics by clicking on the icon in Calypso.

which gives an FFIUnsupportetUntypedLiteral exception.

Problem is the now more strict FFI and the "NULL" passing in calling cairo_scaled_font_text_to_glyphs API within the FFI method CairoFreetypeFontRenderer>>#convertString:len:ofFont:toGlyphs:numGlyphs:x:y:

Same happens when you run examples in AthensTextRenderExamples
