Polygons are now filled with antialiasing, if context_antialias is set.
So are ellipses.
I fixed some clipping bugs.
There is a bug with the AA span though, it's just a little one, but I'm too
tired to find it now. You will see it if you look closely at the top of the
filled ellipse in test/imlib2, using xmag or something.
I'll fix that tomorrow, speed things up a bit, and hopefully implement AA
drawing for ellipse outlines. Oh, I'll unroll some more loops too.
raster: your last commit broke the two test apps. a segv in _RGBA_init()
somewhere, I know it's not my new code, as I tried a fresh checkout and it
did the same thing. I don't have time to check it out tonight though.

clipping rect, but highly suboptimally (I'm not doing proper polygon
clipping here yet, just clipping slowly on each point drawn - really nasty).
There are probably some rounding errors in here. I need to work more on
this, but I have *so* little time for the next few weeks.
Please don't kill me for this code. It's not finished, but I'm about to move
house, and I have to get something working before I pack my PC away.

Hard to come up with a nice API for this, but here's what I have:
ImlibPolygon imlib_polygon_new(int type);
void imlib_polygon_free(ImlibPolygon poly);
void imlib_polygon_add_point(ImlibPolygon poly, int x, int y);
void imlib_image_draw_polygon(ImlibPolygon poly);
Clipping works with these, as demonstrated by test/imlib2
The type paramter may be: POLY_OPEN, POLY_CLOSED or POLY_FILLED (last one
not implemented yet).
I was wondering if draw_polygon should genererate updates, like draw_line.
Thoughts?

Removed all the _clipped functions.
Added imlib_context_set_cliprect(int x, int y, int w, int h) and a
corresponding _get_cliprect.
Set width to 0 to disable clipping (default).
Just use the normal _draw_ functions and it'll do the Right thing.

void
imlib_image_draw_rectangle_clipped(int x, int y, int width, int height,
int clip_xmin, int clip_xmax, int clip_ymin,
int clip_ymax);
Works well. If you make install then cd test, make, ./imlib2, you'll see the
demo/test of the clipping code.
Next up: draw_polygon and draw_polygon_clipped.
Then (eeek) fill_polygon, fill_polygon_clipped, and some clipping for image
blending (fun).

Same as _draw_line but with extra parameters for the clipping region.
Tested and seems to work well. Will check further tomorrow when I convert
geist to use this instead of doing it internally.
Imlib_Updates
imlib_image_draw_line_clipped(int x1, int y1, int x2, int y2,
int clip_xmin, int clip_xmax, int clip_ymin,
int clip_ymax, char make_updates);

-bmp2pt add this too it's command line and it'll bump map to where the
cursor is.
otherwise you will just get bump mapping from an infinite dist lightsource

variable to another filter as willem requested the other day.
eg.
filter( var=anotherfilter( var=13,var=30 ), var=blum );
youcan have as manylevels of filters as you want.
* parser should be quicker, no need to add "NULL" to the end of a
imlib_apply_filter() command.
* some more funky filters should be added soon, at 4.45am i decided to leave
that job till t/m.
