5 years ago I guess maybe this was working via the hidden Ctrl+G toggle, but pull request #295 makes it a first-class feature:
- Allows toggle via Ctrl+G or options menu.
- Persists user selection across sessions.
- Makes it easier to add support for more filtering modes in the future.
Currently the game appears to support only unfiltered textures in OpenGL mode.
It would be nice to get one or more of bilinear, trilinear, anisotropic, etc. filtering options.
It looks like there is unfinished support for bilinear filtering, but no UI or key combo was implemented to actually toggle it.
I've prototyped support for switching between unfiltered and bilinear, with an eye towards adding support towards additional modes (pull request incoming), but it looks like trilinear requires building mipmaps, and anisotropic may be an extension - both of which are currently beyond my abilities.
