Todo list

• Favourites

Small tasks

• Bounds checking when drawing stickman lines (crashes if at top of screen)
• Fix H2 reaction with DESL under high pressure
• Fix neutron cloning - ctype should be NEUT not PHOT. The other reason it doesn't work is that neutrons bounce off, so are never directly on top of clone.
• Vertical flip?
• Make electrolysis of watr/sltw easier?

Medium tasks

• clipboard_pull_text
• Infinite stamps
• Update legacy_mode reactions (and make loads of things unmeltable in legacy mode)
• Fix off-by-one error in fillrect (need to check all boxes are still drawn with the right size/position after fixing)
• Life behaviour (decrement, kill on change to zero) in ptypes.properties

Big tasks

• Move drawing functions to element .c files
• Rationalise number of properties used to describe state - currently have three
• Translations. Will probably involve unicode support and lots of new characters
• Configurable keyboard shortcuts (some work done on this already, not currently on github)
• Element property brush

Hard tasks

• Python without needing it installed on user's machine
• Liquids in radial gravity (must remember to fix heat convection as well)
• Prevent glass from hiding photons and neutrons passing through it
• Fix edge direction detection (does not work at all angles, photons sometimes erroneously killed)

Stickman (some work done on this already, not currently on github though):

• Radial gravity
• Prevent going through walls

Misc

• Water does not put out fire as well as it does in legacy mode
• Oil pressure bug
