Let "make install" do the right thing.

This lets make install do the right thing. Instead of one 16x16 xpm
icon on Linux which looks horrible, you now get a nice desktop icon,
just like for openMSX itself.

Also updated the .desktop file, this matches what is used for the
flatpak. The PNG files are extracted from the ICO file.

And change the .desktop file to reverse DNS notation as the
freedesktop standard nowadays indicates you should use. This also
matches what is mandated by flatpak and will all help to simplify
packaging the next openMSX, not only for flatpak, but also for RPM.

Just a question: isn't that logo of 210x210 a copy of resources/bitmaps/resources/bitmaps/openMSX-Catapult-logo.png?
Did you create all these from the xcf file? Or downscaled the openMSX-Catapult-logo.png?
Anyway, would probably good to have one single source of the same thing, instead of putting multiple copies in the repo. (The downscaled ones may be an exception, but the high-res source should not be copied IMHO... Or can we even derive the downscaled ones from the source during the build?)

[rderooy]

@MBilderbeek I'm a bit hazy on it, almost 2 years after creating the PR. But based on what I wrote back then, they were extracted from the ICO file. I would have preferred an SVG file, but it is better then the default 16x16 image...

Converting images during the build is ugly. It requires that we temporarily install for the build process some tool to convert the image. This is actually what is done right now for both the Fedora RPM package and the Flatpak. And it does not solve the basic problem of "make install" doing the right thing.

e.g.
https://src.fedoraproject.org/rpms/openmsx/blob/rawhide/f/openmsx.spec
https://github.com/flathub/org.openmsx.openMSX/blob/master/org.openmsx.openMSX.yaml

If you want me to drop the 210x210 image, fine. It is not a supported size on Linux anyway.

[MBilderbeek]

What is wrong to require a tool during build? There are already tools required for that, like a compiler... So I don't think that is a bad thing.
I think the 210x210 image is the original one that Eric Boon has drawn. It is probably the source, see openMSX-Catapult-logo.xcf.

[MBilderbeek]

One more question: do the changes still support an installation in /opt?

[rderooy]

Yes the packages can still be installed in /opt if that is what you really want.

As I pointed out, converting the images each time is just ugly. I also consider it a hack to have to convert the images and copy them to the right location outside of make install. make install should do all the work necessary to properly setup the application. This will simplify packaging openMSX for Linux distributions. Just look at the RPM and flatpak files I liked above to see how ugly it is to package openMSX right now.
