[gcompris-devel] Possible extension for scale?

[Wolfram Sang]

Hello,

my girlfriend meanwhile successfully used gcompris in a 4th grade class 
to teach about "weight". As the time pressure of this deadline is gone 
now, I am finally able to ask if you maybe are interested in one of our 
extensions. You can find a screenshot here:

As you can see, the weights are not just "1,2,5,10" anymore. The game 
now works with a granularity of 1g, so the weights in our sets range 
from 100g to 3000g. An additional thing is, that weights of "n * 500g" 
can also be expressed in kg, so the children need to convert the unit. 
(This is an objective for 4th grade maths in Lower Saxony/Germany)

One thing which makes me hesitate is that there may be parts of the 
world, where g and kg are not primarily used? Then again, it is a SI-unit.

At the moment, our extension has an own source-file. Before a possible 
inclusion, I would need to do a bit of refactoring, as I think the 
original scale.c could hold both versions, selectable using "mode". 
Before I do that, I just wanted to know if there is interest and if so, 
my idea of patching scale.c seems apropriate?

Kind regards,
