Keep last chosen measures in Bild menu forms

[josedumoretzsohn]

In the Bild menu, most of forms, such as for "Größe ändern" ("Change Size") and "Leinwandgroßändern" ("Change line for subtitles"), should retain (save) the last measures chosen, in order to enable operational repetition without, as it is now, the need to rewrite the same measure again and again every time we open the form. This would make the editing of a succession of equal size photo frames tremendously easier. Thank you for your attention.
