TextClip Word Wrapping issue

[superfonz]

Expected Behavior

with the method caption in TextClip it should auto break word wise not char-wise in my opinion.
for example if its at the end of a line, something like 'there' will be
'th
ere' with is not helpful.

from moviepy.video.VideoClip import TextClip

text_clip = TextClip(
text='this is a really long text comment so it can be seen that the text clip is not functioning properly.',
method='caption',
size=(300, None),
color='white',
font_size=20,
text_align='center'
)
text_clip.show()

Actual Behavior

the 'is' should not be clipped.

Changing __break_text seemed to have worked :) for pillow verison 11.1.0, looks like there are mismatching methods in older pillow verisions aswell. dependency should be updated.

def __break_text(
        self, width, text, font, font_size, stroke_width, align, spacing
    ) -> List[str]:
        """Break text to never overflow a width"""

        if font:
            font_pil = ImageFont.truetype(font, font_size)
        else:
            font_pil = ImageFont.load_default(font_size)

        draw = ImageDraw.Draw(Image.new("RGB", (1, 1)))
        words = text.split(" ")
        lines = []
        current_line = ""

        # We try to break on spaces as much as possible
        # if a text dont contain spaces (ex chinese), we will break when possible
        for word in words:
            # Try adding the next word
            test_line = current_line + (" " if current_line else "") + word
            bbox = draw.textbbox((0, 0), test_line, font=font_pil)
            t_width = bbox[2] - bbox[0]

            else:

                # If word itself is wider than max_width, split it
                word_bbox = draw.textbbox((0, 0), word, font=font_pil)
                if word_bbox[2] - word_bbox[0] > width:
