Quick and simple solution to a lot of similar problems, use [range].
It needs four arguments, the input range (in this case 0 to the size of your gemwin) as two arguments, and the output range (usually -4 to 4) and it will convert one into the other. Although to make this work on gem you need one for each of the x and y axes.
You can do this by re-scaling yourself, although this does take more time and effort, but also can provide more control. In the end it's your own choice.
[gemmouse] will output coordinates in pixels by default. however, you can specify the range manually, [gemmouse 1 1] will output x=0..1 and y=0..1
