Description

No logs/callstack/whatever, that's a request for a feature. I imagine it as a hotkey toggle, whenever it's on the texture draw function saves every texture/normal map/specular map/etc to a specified folder. Why? Because X360 is relatively old and had pretty decent specs for its time, so game devs have been making their games look better on it. It's very easy to do, so why not? :3

Research direction
The issue requests a hotkey to dump textures to a folder. First, familiarize with Xenia's texture loading code, likely in gpu/ or xenia/gpu/. Check existing discussions in the issue comments for any prior work or design constraints. Research how other emulators implement texture dumping (e.g., Dolphin's texture dump feature). Propose a simple implementation that captures the texture data at the point of loading and writes to disk, ensuring minimal performance impact.
