node size

[1000i100]

i would like to choose node visual size and capacity

• tiny node (for logic gate)
• normal node
• big node and why not small and giant node.

And a scale for the capacity :

• 0.0001 : switch from 0 to 1 on each signal like a boolean
• 1 : default like now
• 2 : need 2 time more signal to go from empty to full
• 4 : need 4 time more signal to go from empty to full
• 10 : need 10 time more signal to go from empty to full
• 100 : need 100 time more signal to go from empty to full

[1000i100]

• 0.0001 : switch from 0 to 1 on each signal like a boolean
• 1 : default like now
• 5 : need 5 time more signal to go from empty to full
• 100 : need 100 time more signal to go from empty to full
