02ebd44851 [shadows] Fix shadows with small blur radius
There's an assertion in calculate_gaussian_kernel() to avoid a division
by zero - due to an unnecessary cast from float to int this assertion
is triggered incorrectly for small (but non-zero) values, e.g. a blur
radius of 1px.

af3ca027a1 [StThemeNode] Add helper method to get the paint allocation
StThemeNodes may have properties - namely shadows - which paint
outside an actor's allocation. This is not a problem unless drawing
is redirected to an offscreen buffer, in which case the actually
painted size is needed in advance when setting up the buffer.

Add a convenience method to calculate an allocation large enough to
paint the node.

a433a1c637 [StThemeNode] Make shadows respect paint opacity
Currently shadows disregard the overall opacity, so e.g. setting
an ancestor's opacity does not effect the shadow. Fix this by
deferring the setting of the shadow's color until it is painted.
Also move duplicated drawing code from st_theme_node_paint() into
its own function.

50c453c54d [StShadow] Add support for spread radius
The (optional) spread radius allows to make the shadow bigger without
enlarging the blur value. Mozilla supports this parameter for the
-moz-box-shadow property.

5060081db5 Move rendering into st-theme-node-drawing.c
The idea behind this move is that we have a lot more control over
rendering if StWidget isn't a big pile of actors, and things are
more efficient.
