wppp_pre_get_posts function

Hey Jeroen!

Thanks for this wonderful plugin.

I’ve been studying the source code lately and come across this function ‘wppp_pre_get_posts( $q, $class )’ in ‘woocommerce-products-per-page.php’ line 305.

Somehow, I couldn’t find where this function is being called.

If you don’t mind, could you explain where is this being used?

Much appreciated!
