Get string width in pixels

Here is the correct way to find text width in pixels

    lv_point_t p;
    _lv_txt_ap_proc(my_str, ctx_text);
    _lv_txt_get_size(&p, ctxi_text, my_font, 0, 0, LV_COORD_MAX, LV_TXT_FLAG_EXPAND);

p.x contains the total width in pixels.

LVGL contains a lot of good resources, but need to dig.

Excellent work.
