Avatar images are scaled with low quality

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Look at the avatar images, downscaled in the chat window (Adium style)
2. Look at the avatar images, downscaled in roster status pop-up balloons.
3. Look at the avatar images, downscaled at the roster items.

What is the expected output? What do you see instead?
High quality scaling (calculated average color for each pixel) expected. 
Instead, I see high quality image only in 3rd case (roster item avatar). In the 
1st and 2nd cases I see images scaled with low quality algorythm (either 
nearest neighbour, or dropped rows/columns).

Please, implement high quality scaling algorythm (calculating average color) 
for displaying avatar images everywhere.

In 3rd I load image from file and scale ше by myself in Qt class, in other 
cases I just send link to image file in HTML element <img/>, and I have no 
possibility to influence the scaling algorithm.
