[ Aesthetics ] Add padding to the text box

[JorgeR81]

Add padding between the text and the node's gutter.

mockup:

• add 2 pixels on the left ( this will help to differentiate the first character, improving readability )
• add 1 pixel on top ( this way, the free space on top, would be equal to the space between lines )

Looks good
