Text Window GUI Padding

[Gurok]

When I tell AGS to use a custom Text Window GUI for speech via:

Code: ags

game.speech_text_gui = gSpeech.ID;

The speech window has 3 pixels of padding on all edges. Is there a way to remove or adjust this padding?

Note: I'm not using any images for the borders. Just a background colour for the GUI and there's clearly 3 pixels of background colour surrounding the block of text. I am using AGS 3.3.0 Beta 12.

It appears there's a hard-coded minimal margin of 5 pixels total for both vertical and horizontal dimension (which may make 2 and 3 pixel padding from respective sides).
