08f6dceef5 gtkcairoblur: Relicense under LGPL
Both Owen Taylor and I, the originators of this code, allow the code
herein be relicensed to the LGPL, which is what GTK+ ships with. This
prevents GTK+ from being GPL-only.

45bdec84f5 gtkcairoblur: Blur a CAIRO_A8 surface instead of a full CAIRO_ARGB32
This is considerably faster to draw and paint.

e9fb8ad1f7 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.
This function was copied (with docs) from Firefox:

65ba8901aa blur: Simplify code
It's always the same code, so there's no need for switch statements.

267d1793c6 blur: Fix pixel sizes
The code accesses pixels in a chunks of 4 bytes, so we must only support
formats where the size of a single pixel is 4 bytes.
Fix RGB24 to be 4 bytes (the alpha channel is ignored) and disallow A8.
