WIP: I added 400 lines for that input display from Record Attack to appear everywhere

alwaydisplayinput in console.

I wrote V_LockBlend. This function just copies an area of the screen to the back screen, and uses it for translucency lookup. This is to just get around ugly overlapping translucency. No OpenGL support though. ;-)

Oh and I added translucency support for V_DrawFill. This time it actually does have OpenGL support.
