v0.3.1: Display options that apply on their own, and the Steam Deck

A small release shaped by playing v0.3.0 on a Steam Deck. As before, you play from your own PAL disc image. Windows and Linux builds are below.

Fixed

• Options > Display: every setting now takes effect on its own. Resolution, Aspect ratio, Texture filtering and Full-height picture no longer wait for the Enhanced preset.
• Fullscreen shows what the window really is, and your choice is kept even when the desktop is slow to switch.
• Vertical sync off now really turns it off, where your desktop allows it.

Improved

• Preset is a shortcut: Original puts the four settings above back to the PS2 picture, Enhanced sets them up for your screen, and the row reads Custom once you change one of them.
• A note under Resolution says it stays at 1x while the CRT filter is on.
• logs/ico-pc.log now records your Display settings and every change to them. Send it with a problem report.

Known limits

• As in v0.3.0: the Direct3D 12 renderer is untested on real hardware, stick and Start/Select prompts are text, .max and .cbs saves are not imported, and the Queen's barrier is drawn at 4:3 in a widescreen picture.
• On the Steam Deck in Game Mode the game is always shown full screen, whatever the Fullscreen setting says.
