In a series of recent changes, some visual control property settings in the *.Designer.cs files were abstracted into the matching .resx files, as a preparation for localizing them. Some (all?) Size and Position elements have incorrect X, Y values (generally over twice the proper values) resulting in visual elements misplaced and mis-sized.
We need to revert the changes for those places where the visual impact is significant, and think again. There may be value in having the positions and sizes in the resource file, to accommodate different lengths of translated text, but the en-us text should use the legacy layout.
Do it in batches, starting with the errors that have been reported on the AWB talk page. This will revert T385373 and T385736.
