1. Fixed an issue where the `opacity` parameter was ineffective when no `background_image` was specified. This was because `chop_image_v2` was converting the shadow image to RGB format, discarding the alpha channel. Consequently, shadows appeared too dark when the background was transparent. 2. Introduced `chop_image_v3` which preserves alpha channel if no background image is specified. 3. Modified `DropShadowV3` to use `chop_image_v3` and pass flag about background presence. 4. This change ensures that opacity is correctly applied even with transparent backgrounds, resulting in more accurate and visually appealing shadow effects.
