Added \blur tag for real gaussian blur. Blurs the same things as \be, except in a prettier way.
...
It is possible to combine the two, although it'd be mostly pointless.

Ensure Rasterizer::mWideBorder is initialized such that memory allocation in Rasterizer::Rasterize() doesn't go crazy. Also fix brainfart causing \xbord0\ybord<nonzero> to draw no border.

Enable variable strength 'blur edges' effect, using other values than 1 to \be, like \be20. Also allow putting \be inside \t for animating the blur effect.
...
The parameter is the number of passes of blur to perform.

Implemented four new tags: \xbord \ybord \xshad \yshad
...
Allows setting the border in X and Y direction separately, and the shadow displacement in X and Y direction separately.
The \xshad and \yshad tags also allow negative shadow displacement values. Negative shadow is still not allowed in any of the traditional locations.

Fix rendering bug exposed with \be1, \bord smaller than 1.5 and non-zero fill alpha, causing "stray dots" to appear.
...
The problem was caused by an integer underflow, the fix involves spending a few more instructions per pixel to avoid that.

Back to classic pixmix/pixmix2 architecture. Probably made some parts clearer. More and more correct documentation of the Draw code. Probably more correct (at least not less correct, it seems) alpha calculation.
