I just uploaded a new version of Win32Dib (0.4.0) to my website
(http://users.pandora.be/tommycarlier/eu). This new version has some features
that might be useful for your project:

-> translucency: drawDibToDib and drawTransDibToDib (transparent bitmap) now
have an extra argument 'alpha'. This is an integer between 0 and 255. 0 means
fully transparent, 255 is fully opaque, and anything in between is translucent
(partially transparent). Check out the demo tiledib.exw to see the effect.

-> applyDibBrightnessToDib: this new procedure is just like drawDibToDib, but it
doesn't draw the source bitmap colors to the destination bitmap: it just copies
its brightness/lighting. You could use this to apply a pattern to a flat-shaded
bitmap. In your project, you could apply the original lighting of the wall to the
new pattern. Check out the demo manip.exw: 'Apply Brightness' applies the
brightness of a bitmap (containing horizontal lines) to the original bitmap.

PS: EuMario: I haven't added a bit depth reducer (yet), but now there is a
saveDibGray-function that saves a bitmap as an 8-bit grayscale BMP-file. The
advantage: smaller file + you don't have to make the bitmap gray yourself (bitmap
itself stays intact).
