Where does zen_draw_form function definition reside?

[MaxPowers]

I cannot find the text "function zen_draw_cart" in any of the files. Which of the many, many files does this function reside in?

function zen_draw_cart

Quite confusing between your subject name and text description of this topic ...

However, if you're still referring to zen_draw_form, it is originally located under your includes/functions/html_output.php and admin/includes/functions/html_output.php file.
