Widescreen titlepics display incorrectly on BFG IWADs

[wildweasel]

Reporting this one for Adam on the ZDoom Discord, to investigate more closely later: it seems that the widescreen title and credits pics (at least the ones for Ultimate Doom, unsure about Doom 2) do not display at the right aspect ratio if the IWAD is one of the BFG Editions.

The titlepic gets crunched into 4:3 when it should be 16:9, and the credits pic mysteriously gets cropped to 4:3 and then stretched to 16:9.

I (or somebody) will need to confirm this at some point.

(edit) I've observed that Adam is also using high res packs and upscale settings, so these are also things to investigate with this bug.

The most important thing to have here is the config with which it happens.

Okay. I asked the reporter for his INI file via Discord - here it is. I haven't had the chance to examine it myself yet.

No problems here with that config. So it's likely to be caused by the hires packs. The general advice with hires packs is to disable widescreen content because it might get in the way of how texture dimensions are determined.
