This PR makes a number of simplifications to the layout and constraint features that were added after v0.25.0. For users upgrading from v0.25.0, the net effect of this PR (along with the other PRs) is the following: - New `Flex` modes have been added. - `Flex::Start` (new default) - `Flex::Center` - `Flex::End` - `Flex::SpaceAround` - `Flex::SpaceBetween` - `Flex::Legacy` (old default) - `Min(v)` grows to allocate excess space in all `Flex` modes instead of shrinking (except in `Flex::Legacy` where it retains old behavior). - `Fill(1)` grows to allocate excess space, growing equally with `Min(v)`. --- The following contains a summary of the changes in this PR and the motivation behind them. **`Flex`** - Removes `Flex::Stretch` - Renames `Flex::StretchLast` to `Flex::Legacy` **`Constraint`** - Removes `Fixed` - Makes `Min(v)` grow as much as possible everywhere (except `Flex::Legacy` where it retains the old behavior) - Makes `Min(v)` grow equally as `Fill(1)` while respecting `Min` lower bounds. When `Fill` and `Min` are used together, they both fill excess space equally. Allowing `Min(v)` to grow still allows users to build the same layouts as before with `Flex::Start` with no breaking changes to the behavior. This PR also removes the unstable feature `SegmentSize`. This is a breaking change to the behavior of constraints. If users want old behavior, they can use `Flex::Legacy`. ```rust Layout::vertical([Length(25), Length(25)]).flex(Flex::Legacy) ``` Users that have constraint that exceed the available space will probably not see any difference or see an improvement in their layouts. Any layout with `Min` will be identical in `Flex::Start` and `Flex::Legacy` so any layout with `Min` will not be breaking. Previously, `Table` used `EvenDistribution` internally by default, but with that gone the default is now `Flex::Start`. This changes the behavior of `Table` (for the better in most cases). The only way for users to get exactly the same as the old behavior is to change their constraints. I imagine most users will be happier out of the box with the new Table default.
