[blueprint theme] textfield and combo box are different from the gtk theme engin

In the image attached to this bug report you'll see that there are two bugs :

- The First letter in the textfield would need to be offsetted by few pixels.
- The combo button is not scaled according to the textfield scaling (look
   at the dark grey line and the white line)
