# Objective

`GlobalTransform` after insertion will be updated only on `Transform` or
hierarchy change.

Fixes bevyengine#9075

## Solution

Update `GlobalTransform` after insertion too.

---

## Changelog

- `GlobalTransform` is now updated not only on `Transform` or hierarchy
change, but also on insertion.

…on_texts`

and `GlyphBrush::process_glyphs` each have a section of code that calculates the minimum bounds around a list of text sections.

The first two functions don't apply any rounding, but  `process_glyphs` also floors all the values. It seems like this can cause conflicts where the text gets incorrectly shaped.

Also when Bevy computes the text bounds it chooses the smallest possible rect that fits all the glyphs, ignoring white space. The glyphs are then realigned vertically so the first glyph is on the top line. Leading empty lines are missed off.

This PR adds a function `compute_text_bounds` that replaces the duplicate code, so the text bounds are rounded the same way by each function. Also, since Bevy doen't use ab_glyph to control vertical alignment, the min y bound is just always set to 0 which ensures no leading empty lines will be will missed.

There is another problem in that trailing empty lines are also ignored, but that's more difficult to deal with and much less important than the other issues.
