plain terminal output

The game used to work fine with all graphical options enabled/maxed out.
Since Wine-9.13 most of the textures are missing in-game when soft shadows
option is enabled. The menus and the intro/in-game videos are not affected.

The problem is present since
commit 272c55ac257315ef8393df357a79aac4e0d6cd76
opengl32: Add default implementation for wglChoosePixelFormatARB.

The default implementation will be used automatically if the driver
    populates the wgl_pixel_format ARB fields.

Reproduced with both the Steam and GOG versions. No mods or unofficial patches
were installed.
