This will fix: #428

Changes so far:

  • Skip image processing when preview panel is closed
  • Add colour caching to reduce redundant colour space conversions in image
    processing. Cache previously converted colours to avoid repeated RGBA->termenv
    conversions of identical pixels.

So far, this means that:

  1. No lag occurs when navigating directories with large images while preview is hidden
  2. No lag occurs when performing other operations (e.g renaming files) within directories with large images while preview is hidden
  3. Eliminates repeated colour conversions for duplicate pixels
