[Fixed] ENDOOM doesn't cover entire screen

Regardless of resolution, it appears that there is a small strip on the right edge of the screen that still shows the previous image.

I can't take a screenshot of it, since the window immediately closes if I press any key or click anywhere.

Would need to capture a video and then extract a frame from that video. A bit overkill, probably...

Yeah, that did the trick. The TITLEPIC is just peeking right there.


Seems that it's just the ENDOOM itself that isn't drawing correctly, the "press any key" text covers the full width of the screen.

Sometimes it is really interesting how bugs manifest themselves.
In this case the cause of the problem was a bad range check in the character drawer for the text screen which skipped the rightmost column.
This meant that this rightmost column was transparent and didn't cover what it was supposed to do.

The start screens only have one shader available (textured, with alpha test - the rest only gets loaded after the screen is up) so they can neither use ClearRect nor not fully opaque textures for covering the screen, they actually need a fully opaque texture.
