SpookyGhost r84: File dialog navigation and revised icons

[encelo]

What’s New in This Release?

Improved File Dialog Navigation

The file dialog now remembers your directory history. Use the new left and right arrow buttons, or your mouse’s extra back and forward buttons, to quickly jump through previously visited folders. Plus, there’s a handy arrow-up button to move directly to the parent folder of your current selection.

Smarter Animation Controls

The Stop, Pause, and Play buttons that appear throughout the interface are now context-aware. Buttons that don’t make sense for the current animation state are disabled. For example, the Play button is disabled when the animation is already playing, reducing confusion and improving workflow.

Refined Icons

Several icons, such as those representing animations and rendering, have been redesigned for clearer and more intuitive visualization.

Updated to Dear ImGui v1.92.1

The application now compiles with the latest Dear ImGui version, ensuring better UI stability and improvements under the hood.
