## Why It's Good For The Game

Remade sprites for t-ray scanner, gas analyzer, geiger counter and hand
drill to fit current art style. Now they look juicier and thicker, i
guess.

## Changelog

* Medical/improvised gauze icons (#81802)

## About The Pull Request

Adds icons for stacks of medical gauze and improvised gauze, so that
they can be differentiated from stacks of cloth. Currently all 3 look
the same. Medical gauze is blue tinted like the medical tape, improvised
gauze is grey and a smaller size than medical gauze. Both have
attachment clips at the edge of the roll.

## Why It's Good For The Game

Easier to tell three different items apart at a glance.

## Changelog

* Readability Pass to Advanced Medical Tools (#82225)

Update the sprites of the advanced surgical toolset, giving them
distinct colors and updating their lighting to reduce shades and
increase visual readability at normal resolutions.

Currently, the advanced surgical toolset over-relies on the tooltip to
communicate item state quickly and accurately. This PR adds both color
differentials, and enhances the shape of the existing tools to help a
player tell them apart quickly and accurately. Additionally, it assists
in defining the general shape of the item with cleaned up shading to
decrease noisy patterns in the sprite.
