-- if the FontManager list is empty, scan the font list

-- If the UI has never been shown, as would always be the case on a render node,

-- nothing will scan the font list for available fonts. So we check for that here,

-- and force a scan if needed.

if not next( FontManager:GetFontList() ) then FontManager:ScanDir()

end

if req:IsQuick() then

quality = 1

end

-- the drawstring function is doing all the heavy lifting

drawstring(out, font, style, size, justify, quality, cx, cy, Pixel{R=r,G=g,B=b,A=a}, text)

OutImage:Set(req, out)

end

The Process.Function in this Fuse will get 11 variables from the UI, Text strings, fonts and metrics, color and on screen location. If no font list is populated it will force the scanning of the Font list from the OS.
