Bino Mask [bino_mask][proof of concept]

Places a black mask with a circular window in Zoom mode.

When this mod is enabled, pressing the 'Z' key (zoom) will give the following (if in creative mode, or have binoculars).

Note that this is a proof of concept only, with many limitations.

• Minetest source code needs to be patched to detect state of 'Z' key.
• Reads aspect ratio from minetest.conf at startup, so can't use multiple aspect ratios or change aspect ratio without restarting server.
• Some lag between zoom and mask changes.

However, for this mod to work, the minetest source needs to be patched with the provided patch file, which was generated using a recent 5.0 development version of minetest. Note that both the server and client need to be patched.
