Don't to be too much severe with yourself... at least you are an 
lua programmer... ;) 

The repeated use of setfullscreen({smaller}) does not guarantee you
to obtain the same screen resolution on different hardware
(some graphic card could skip certain resolution)  

With my proposal you could direct switch to a particular screen resolution,
and before (with getscreenmodes) you could check if it is supported
by the hardware.

So you have write the article in the wiki... I checked and it seems good.

I tryed also and It work fine. I don't think there are some contraindications.

Did you have tried some lua code to do that?
(You still thought to not to be a programmer? :) )
I will try to implements...

I think video patches needs a more exhaustive analysis, but 
I don't think that your idea was stupid,
it could be an initial workaround to satisfy the lack of video patches,

I'm thinking to publish on wiki some "libraries" that add some
lua objects to simplify from the programmer point of view some things,
adding functions that aren't directly implemented by pipmak. 

I have thought to these:

color.lua     to get better management of colors
dialog.lua    to use some simple dialog box (text,button,check box and so on)
animation.lua to simplify animation (and we could put here your idea)
inventory.lua to manage inventory list
others?

all of them will be included with 
  pipmak.dofile("lib/<library_name>.lua")
in main.lua

All of this libraries use actual pipmak function as elementary bricks and
with the development of Pipmak some library functions could
move directly in the Pipmak code... 

I have already prepared "color.lua" for my autocubic project
(which I would that it was a library too) with these methods:

-- c=newcolor(string)   htmlcolor|{dark|light}colorname
--                      accept "FF8092" like HTML or colorname
--                      red,blue,yellow,darkred,lightyellow,...
-- c:setcolor(string)   htmlcolor|{dark|light}colorname
-- c:getRGBA()          return r,g,b,a
-- c:invert()           invert color
-- c:brithness(br)      br=1:white   br=-1:black   
-- c:alpha(a)           set alpha 
-- c:Red(r)             set red 
-- c:Green(g)           set green
-- c:Blue(b)            set blue 
-- c:tostring()         return string rappresentation 


Example of use:

c1=newcolor("red")     -- use colornames
c2=newcolor("00FF00")  -- use color strings as HTML code

patch1:setcolor(c1:getRGBA())  -- set patch color

c1:brithness(0.5):Red(0.2)   -- make color lighter and
                             -- increments red component

img:color(c2:getRGBA()):fill()  -- fill img using c2 color
                                -- (needs pipmak build 155)


"dialog.lua" is still in development (it needs pipmak build 155 to work):

Here an example of use:

d1=newdialog{x=70,y=70,h=300,w=300,
             title="Title of the dialog",
             title_bgcolor=c1,
             title_fgcolor=c3}
d1:setfont{size=20}
d1:text{"Welcome",align=pipmak.center}
d1:text{}     --leave a empty line
d1:setfont{}  --return to standard font
d1:text{"This is a preliminary dialog object.\nBye"}
d1:show()     --show dialog window


I NEED remarks to known if this idea of libraries is good or not.
Or if better implements all in pipmak code.
Fabrizio, Christian and all other pipmakers, what do you thinking about?
