if gradients were set (>0) then the images are not loaded into texture
objects. the gradients are applied somewhere else in the code, around
the time of the first draw IIRC. I did notice that the gradient (in
texture objects) affected more different objects that the textures
did, some of the image texture (objects) are reused in the code
somewhere

check the source I posted, (from memory) there are:
left -> right - color1-color2 (right -> left)
top -> bottom - color1-color2 (bottom -> top)
l2r color1->color2-color3 (r2l) with optional steps
t2b color1->color2-color3 (b2t) with optional steps
not sure what the other one is, maybe "dimple effect"
(t2b+l2r+color1-color2-color1) like for widgets

I was thinking about the memory block that gets created at boot time,
if all structs use the largest definition (the algorithm that has the
most data) then replacing that memory block becomes a lot easier

thanks, this might work for preview, if you can also unload
that is a start, is there a way to "unload" that same grd file. or
load an empty one

cat you also make it read a specific config, like:
$echo -n "#$<filename.cnf>"

I will have a play, see how useful they are, try to do the black and
white ones I promised
