A transparency option on the use of colour so that perfect antialiasing

I thought that was already available. I have certainly been able to
superimpose two pictures so that you could see both through each other,
if you see what I mean.

It depends on what you mean by available.
George has written about merging colours on screen to give a transparent
effect (Quanta v27i4).
But the pic/psa standard does not support alpha values.
Modern PE sprites do support them and they can be used instead as a
picture format.
PNGCONV (a w$ program) can convert png files to sprites and keep any
transparency that is set.

EDDICON (a QL sprite program) can read bmp or pic files and set an alpha
value for each pixel up tp 128x128.
Or you can create sprites from scratch.

Also BMP2SPRT can convert bmp to sprites and change a given colour to an
alpha value.

The sprite definition provides room for new options but are not
implemented so far.
How about fading transparency?
