Center each text line individually when drawing on image

Browse source 
Updated text rendering logic to center each line horizontally
based on its estimated width, ensuring multi-line text is
visually centered. Previously, all lines were drawn at a fixed
horizontal position. Both shadow and main text now use the
calculated centered position.
