[Xcb] xcb_poly_rectangle width and height

[trebol55555 at yandex.ru]

I don't understand the design of these requests (I'm talking about the
X server).

PolyRectangle:

You say to the server: draw a rectangle at (x, y) with width "width"
and height "height". And the server draws a five-point PolyLine:

[x,y] [x+width,y] [x+width,y+height] [x,y+height] [x,y],

That is, a rectangle of width "width" + 1 and height "height" + 1
???????????

PolyFillRectangle:

You say to the server: fill a rectangle at (x, y) with width "width"
and height "height". And the server draws and fill a rectangle at (x,
y) with width "width" and height "height". Good? Noooo! It's even worst,
because what the server is doing is filling the FillPoly:

[x,y] [x+width,y] [x+width,y+height] [x,y+height] [x,y],

but in this awkward way, if this is the rectangle specified by these
points


ooooooo
o     o
o     o
ooooooo

the server draw this (only #):

######o
######o
######o
ooooooo


Am I missing something?
It's like a joke!
