This is considerably faster to draw and paint.

css: Fix computation of pixels occupied by blur radius
...
These computations were done randomly in lots of places and more often
than not, they were also wrong.

blur: Fix pixel sizes
...
The code accesses pixels in a chunks of 4 bytes, so we must only support

Fix RGB24 to be 4 bytes (the alpha channel is ignored) and disallow A8.
