vcl tiled rendering: avoid 'Pixel represents color values!' warnings
Which happens e.g. during rendering tiles:
OutputDevice::BlendBitmapWithAlpha() produces an RGB alpha
(255,255,255), then tries to set a pixel in the 8bit alpha channel using
it, so when BitmapReadAccess::SetPixelFor_8BIT_PAL() tries to get the
color index, we try to get it from a color that is not indexed.
Let's assume that when the color is not indexed, it's always gray, so it
doesn't matter what color we pick for the alpha mask needs.
