I can't find the screenshot atm, but you had a message box with the > selector "path" in it, followed by a series of numbers.> What does that message do?
I don't really understand the question but I think this is my mistake, I didn't notice how the functions were displayed :
The wrapper offers a layer structure called *t_elayer *that owns a set of points. First we create a layer for a t_ebox (GUI object) : ebox_start_layer(t_ebox *x, t_symbol* name, float width, float height)
To create a path, you can use several functions : egraphics_move_to(t_elayer *g, float x, float y), egraphics_line_to(t_elayer *g, floatx, float y), egraphics_curve_to(t_elayer*g, float ctrl1x, float ctrl1y, float ctrl2x, float ctrl2y, float endx, float endy), ect... The functions append points to the t_elayer.
Before drawing all the paths, we apply the matrix transformations and mark the layer ready to be drawn : ebox_end_layer(t_ebox *x, t_symbol *name)
Then we paint the layer : ebox_paint_layer(t_ebox *x, t_symbol *name, float x_p, float y_p)
if something has changed (an attribute or whatever you want) and we need to repaint a layer, we invalidate the layer with : ebox_invalidate_layer(t_ebox *x, t_symbol* name)

Yeah, the C code looks like a fairly typical 2d API. I was just referring to what I saw in the screenshot, with message boxes I assume you were using to draw a mustache on Mona Lisa in the running instace of Pd. But I probably misunderstood what you were doing.

Just curious-- in the features you mention translate and rotate, but not scale and skew. Is there a reason for that?
