Transparent .pacs? new to 1.94b?

[ScouseJedi]

As part of my track texturing I normally draw a big bright arrow on my texture so that I get it all running in the correct direction.

The first colour I chose was pink (255, 0, 255)

When I coverted this .gif to a .pac and looked in buldozer I saw that the pink was not there and was in fact transparent. I went in game (1.94b) and the same was happening there.

Is there a performance hit compared to .paa's

Its a lot easier that buggering around with alpha channels. (unless you want a pink car then you are in trouble - and dirty glass I suppose)
