BUT: It doesn't rescale when I resize the widget. So I guess I do still need a resize() method to handle that still?

I tried it and it works, but on Windows, with a certain .svg I got:

D:\a\mrv2\mrv2\BUILD-Msys-amd64\Release\mrv2\src\mrv2-build\lib\mrvWidgets\mrViewer.cxx(1529): error C2026: string too big, trailing characters truncated

I am attaching the .svg that I think is the issue.
Hmm, just dropped that SVG file into my little fluid test, and it seems to work OK. Is it possibly a different image that is causing the issue?
(I got a grey image showing a white outline, with a drop-shadow, of a stylised hand wiping a cloth over the surface; which seems like a credible image for a "scrub" icon, so I assume that is working OK.)

So, as a possible workaround, I tried storing the SVG file in "compressed" form in fluid, as Matt had suggested. That certainly makes it small enough (down from approx. 20K text to approx. 7K) but I can't then seem to get Fl_SVG_Image to load it, so... One for Matt maybe? As I am out of ideas now:

Here's the adapted fluid file, test2.fl:

=========== test2.fl ============

# data file for the Fltk User Interface Designer (fluid)
version 1.0400
header_name {.h}
code_name {.cxx}
decl {\#include <FL/Fl_SVG_Image.H>} {public global
}

decl {\#include <FL/Fl_Box.H>} {public global
}

data svg3 {private local filename {Scrub.svg} compressed
}

class svg_rsz {open : {public Fl_Box}
} {
Function {svg_rsz(Fl_SVG_Image *svg2, int X, int Y, int W, int H, const char* L=0) : Fl_Box(X,Y,W,H,L)} {
comment Constructor open
} {
code {svg = svg2;
svg->resize(w(),h());
image(svg);} {}
}
Function {resize(int x, int y, int w, int h)} {
comment {A resize method} open return_type void
} {
code {Fl_Box::resize(x,y,w,h);
svg->resize(this->w(),this->h());} {}
}
decl {Fl_SVG_Image *svg;} {private local
}
}

Function {} {open
} {
code {Fl_SVG_Image *svg2 = new Fl_SVG_Image(NULL, svg3, svg3_size);} {selected
}
code {svg_rsz *boxA = NULL;} {}
Fl_Window main_win {open
private xywh {882 285 249 221} type Double resizable
code0 {boxA = new svg_rsz(svg2, 15, 15, 180, 180);} visible
} {}
}
