Artiflash graphic's colors are corrupted

When you use an item from your inventory in Heretic and Hexen, an animated graphic appears briefly in place of the used item on the status bar/HUD. The graphic's colors are drawn corrupted. The colors the graphic are drawn in aren't always the same, it seems; they differ if I start a new game, for example.

In GZDoom 4.3.3, the graphic appears fine.

Here's a screenshot demonstrating the problem:

And here's my configuration file, in case it's needed:

Bisected down to this commit. There seem to be two issues at work here:

1. The "artiflash" icon is drawn as a translatable image. However, the original graphics do not have any colors that correspond to the player's translatable color range. It is rather questionable why the DI_TRANSLATABLE flag is set for this call.
2. The real bug: translatable images are not drawn properly in Heretic and Hexen since the aforementioned commit.

I'm currently investigating this issue further.

Found the problem: extra player translation tables were not fully initialized. Submitted a PR to fix this.
