Tooltip issue / Suggestion with scaling mode

Issue with rendering gui mode for tooltips, suggestion add a 25_slice mode to allow better stripping images , and have more variations to dont have these problems.

How is supossed to look:

Reference:

For Fist Image the json frame is
{
"gui": {
"scaling":

{ "type": "nine_slice", "width": 100, "height": 100, "border": 10, "stretch_inner": true }

}
}

 

For the second is
{
"gui": {
"scaling":

{ "type": "nine_slice", "width": 100, "height": 100, "border": 10, "stretch_inner": false }

}
}
