Distance between "ATLAS" and following text too small

Hi @fsauerbu,

I realised that the distance between "ATLAS" and text that follows the branding is smaller than a space in that text (i.e. if you specify "Simulation Internal", the distance between "Simulation" and "Internal" will be larger than the distance between "ATLAS" and "Simulation")

Is this the intended behaviour? If not I'd suggest to adjust this distance (atm it is 0.23 * font_size * PT) to something like 0.4 * font_size * PT. I can create a MR for that and update the test plots.

See plots below for clarification

Current implementation:

With 0.4 * font_size * PT:
