VSN1 LCD: transparent text / no black background behind glyphs?

Hi all,

When I render text over a coloured LCD area using Lua (for example with ldft), each character appears with a black rectangular background instead of showing the colour beneath it.

Is there already a way to render text with a transparent background, or could this be added to the Lua LCD API? Ideally, the text function would either draw only the glyph pixels or accept an optional background/transparent parameter.

This would make it possible to place labels cleanly over coloured panels, gradients, and artwork without first repainting a black rectangle behind the text.

Best,

Istvan
