Instead of having 3 nearly identical loops, it probably worth moving all the code (ellipsis and draw parts) to the helper function and calling it for the shadow, outline, and text.

I'm sorry if it's not the best, moving them to a helper function will be complicated for me, I may need some help.

The three of them are calling three different functions and running under different conditions and also changing three different variables and calling x advance at the end for 2 different variables, a helper function will require more checks and will take so many arguments and will run much more conditions for each loop to do the same.

The only code which is identical is this :

        if (trim_pos >= 0) {
	        if (rtl) {
		        if (j < trim_pos) {
			        continue;
		        }
	        } else {
		        if (j >= trim_pos) {
			        break;
		        }
	        }
        }

The only way to prevent repeating is to loop once without drawing and to save the glyphs that should draw to an array, then looping over it three times in order. [shadow] -> [outline] -> [main text], this depends on the cost of constructing a new Glyph in every loop inside draw function or creating a Vector to store each glyph separately in an array with it's own structure. we better draw them after looping over all lines, to insure that a line's shadow never overlaps over previous lines.
