[Tuxpaint-i18n] Translation of tuxpaint software

[Jacques C. <jac...@or...>]

Hi,

while checking the po file for tuxpaint, i found the sentences :

- Xor colors
- Click and drag to draw a XOR effect
- Click to draw a XOR effect on the whole picture

As the excellent software tuxpaint is designed for children, i do not 
think that 'XOR' has a meaning for them.
Is there another way, comprehensive by a child, to describe this effect ?

Best  regards

Jim
