Hi, I'm trying to use Cairo to draw on a SDL surface (i.e. an image
Following this page (https://www.cairographics.org/SDL/), drawing
works fine but I can't get subpixel rendering working for fonts.
From the doc it seems the only thing to do is to set a

I can get
grayscale antialiasing but never RGB.
I've seen that surfaces also have a cairo_font_options_t but that this
be changed. So my questions are:
- Is it supposed to work or not ?
- What factors determines how fonts get drawn (context, surface, other
things... ) ?
- Is there a way to get RBG subpixel rendering working with SDL ?
