I think TLF handles all of that in BaseCompose.as. It looks pretty complex and
will depend on how complex your text is.

Well, I have managed to make my custom background to be invoked by the
framework,
However I'm having a tough time calculating the height of the background to
cover all the space between two lines.
Specially when lines have different sizes and using lineHeight in the style.
How can I get the space between two textlines? I mean the line totalHeight +
any other space TLF or Flex adds between the lines.
Background alignment starts geting uggly when I add styles like:
{
lineHeight:"120%";
leadingModel:box;
dominantBaseline:auto;
baselineShift:-4;
alignmentBaseline:useDominantBaseline;
}
maybe my styles are wrong
