Glk: Image scaling in buffer windows

[kamineko (Drew Cook)]

Ah, nice. I thought I had to do something! I’d love to stop including two sizes for every image in my games, this is good stuff. Thanks!

I’ve added support for Glk 0.7.6 to Windows Glk, and made new builds of Windows Glulxe and Windows Git with it:

These are also on GitHub:

Very good, thank you.

Even without any fancy new Glk invocations, this changes the default behavior: images will now be scaled down to fit the screen width if necessary, instead of drawing them at full size and cutting off the edges. So everyone will get that benefit if they’re playing on a new interpreter: you can draw all your images at the highest resolution you have, and trust the interpreter to display them in a useful way.

@Dannii, is Parchment going to automatically scale down images in text buffer windows, too?

When I get around to implementing it, it will!

I’ve now implemented this in RemGlk-rs/Emglken/Parchment!

The GlkOte docs aren’t up to date. But I also saw that the docs in Github specify the new properties for graphics windows even though they aren’t used.
