3.22.21: gtk murrine engine dependencies and other gtk 2.x dependent themes

[kloczek]

Looks like some mate-themes themes depends on gtk murrine engine which is no longer available and only supperts gtk 2.x.
I thoing that it would be good to make decision about take over gtk murrine engine mainatainance or remove those themes from source tree as mate desktop compeltly swithed to gtk 3.x.

I'm not sure but I thing that currently there are more gtk 2.x parts.

Which distro are you using that doesn't have gtk2-engines-murrine available?

[kloczek]

I'm talking about what is in the git tree.

[kloczek]

Again .. gtk2-engines-murrine is for gtk 2.x which is no longer used by mate components.

[smurphos]

Yep but people may still be using GTK2 apps on distros with MATE as the DE, so the themes still have to support GTK2, and GTK2 themes will generally always rely on some engine package or another.

[kloczek]

Only gtk 2.x application is gimp.
As preparation I would suggest at least add option to not check and install all gtk 2.x stuff.

If you will look closet on that list you will find that ~85-90% of that packages are already unmaintained by source tree maintainers.
Many of that projects like gtk2-engines-murrine even web page and repository gone from public network.

So long as any packages distros ship and people USE are using GTK2, we need to support it in our themes. Note that it is often possible to use the pixbuf engine to duplicate theme elements from GTK3, I had to do a lot of such widget screenshotting in my UbuntuStudio_Legacy theme
https://github.com/lukefromdc/gtk-theme-ubuntustudio-legacy
both to port what murrine did in GTK2 to GTK3, and in some cases to backport things from GTK3 to GTK2.

I had to screenshot what Murrine did with menu entries and check/radio buttons and use those in my GTK3 theme, could of course use them in both GTK3 and in GTK2 if murrine ever goes away outright. My guess though is the theme engines and GTK2 go away at the same time, so we need not worry about this
