Description
TF2's item model panel will automatically generate icon textures for items without pre-rendered icons (ex. any weapon with a war paint or festivizer). These textures are sized to the exact dimensions of the item model panel that uses them, so they shouldn't need any filtering to look correct wherever they are used. Despite this, these textures are still resampled when they are rendered, causing them to look slightly blurred:
This PR configures item model panels' auto-generated textures to always use point sampling, allowing them to be rendered pixel-perfectly without any filtering artifacts:
(Note: I would appreciate if anyone could test this PR on a 4K monitor to ensure this doesn't create any visual regressions on high-res displays.)
