Inside the RscShortcutButton class the TextPos class determines the control's text position.

class TextPos
{
left = 0;
top = 0.05; // Sets text absolute Y position on the control. Not relative to the button height
right = 0.005;
bottom = 0.000;
};

This is a problem when working with different height of RscShortcutButton buttons because TextPos->top needs to be defined for each control

also the interface size seems to also effect the text position. User with smaller interface size can get the text rendered on different position than originally intended

It would be best if there would be automatic text centering
