Blur using SVG filters
The Inkscape team has just released version 0.45, and it includes initial support for SVG filters. The first one implemented is Gaussian Blur. Raquel Ravanini was quick to try it in KMahjongg tiles. Notice that we already have shadows, but these are currently made of several gradients put together. They look good, on most cases, but the seams are difficult to manage. This screenshot shows the new tile using a simple Gaussian Blur filter (right), and our current approach (left).
In the case of this particular tileset the difference in rendering is not significative, but having support for the SVG filter in Qt/KDE would make the life of the artist easier, and the filesize smaller as well.
