[PATCH] Fix rect position when trasnforming to view coordinates

[Jordi Fita <jfita@xxxxxxxxxxxxxxxxx>]

Hello,

I sent attached to this letter a patch to view-helper's
model_rect_to_view_rect() function that computes the position of view
rectangle correctly--instead of subtracting the rectangle's coordinate
from the scaled position, it subtracts the widget's position.

With this patch, gegl-gtk-paint works better.


Regards,

Jordi
