Release [`v0.33.0`](https://github.com/go-hep/hep/tree/v0.33.0) is out of the oven.
This release contains no major API breakage, but all around improvements and bug fixes.
## cmd
- [cmd/hepmc2root](https://pkg.go.dev/go-hep.org/x/hep@v0.33.0/cmd/hepmc2root): is a new command to automatically convert HepMC2 ASCII files to flat n-tuples ROOT files.
```
$> hepmc2root -h
hepmc2root converts a HepMC2 ASCII file into a ROOT file and (flat) tree.
Usage: hepmc2root [OPTIONS] hepmc.ascii
Example:
$> hepmc2root ./hepmc.ascii
$> hepmc2root -o out.root -t mytree ./hepmc.ascii
Options:
-o string
path to output ROOT file name (default "out.root")
-t string
name of the output tree (default "tree")
```
## hplot
`hplot` has been migrated to the new [Gio](https://gioui.org) API, and needs [Gonum/plot@v0.13.0](https://pkg.go.dev/gonum.org/v1/plot@v0.13.0).
Slight differences are to be expected in the rendering of plots.
With the new `Gio` version we are using, you may need development headers for [Vulkan](https://www.vulkan.org) on [Linux](https://kernel.org/).
See the installation instructions of Gio for more details: [Gio Installation](https://gioui.org/doc/install)
- fix a bug in `hplot.TiledPlot.Plot(i, j int)` where the `*hplot.Plot` returned by `Plot(i,j)` was actually the conjugate of what the documentation specified. Now, `Plot(i,j)` returns the plot as documented.
## sliceop
- introduce a generic `sliceop.Resize` that can reuse `[]T` capacity
- introduce generic versions of `sliceop.Take` and `sliceop.Find`
