Describe the bug

I created an SVG image containing text using Inkscape. I have bundled the image into a simple program to display the image, but no image is displayed. If I create an image with text and other objects, the objects are displayed but the text is not.

Here is the content of bundled.go as generated using the instructions below:

var resourceTextSvg = &fyne.StaticResource{
	StaticName: "text.svg",
	StaticContent: []byte(
		"<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"no\"?>\n<!-- Created with Inkscape (http://www.inkscape.org/) -->\n\n<svg\n   width=\"210mm\"\n   height=\"297mm\"\n   viewBox=\"0 0 210 297\"\n   version=\"1.1\"\n   id=\"svg1\"\n   inkscape:version=\"1.3.2 (091e20e, 2023-11-25)\"\n   sodipodi:docname=\"text.svg\"\n   xmlns:inkscape=\"http://www.inkscape.org/namespaces/inkscape\"\n   xmlns:sodipodi=\"http://sodipodi.sourceforge.net/DTD/sodipodi-0.dtd\"\n   xmlns=\"http://www.w3.org/2000/svg\"\n   xmlns:svg=\"http://www.w3.org/2000/svg\">\n  <sodipodi:namedview\n     id=\"namedview1\"\n     pagecolor=\"#505050\"\n     bordercolor=\"#eeeeee\"\n     borderopacity=\"1\"\n     inkscape:showpageshadow=\"0\"\n     inkscape:pageopacity=\"0\"\n     inkscape:pagecheckerboard=\"0\"\n     inkscape:deskcolor=\"#505050\"\n     inkscape:document-units=\"mm\"\n     inkscape:zoom=\"0.2102413\"\n     inkscape:cx=\"394.78447\"\n     inkscape:cy=\"561.25984\"\n     inkscape:window-width=\"1312\"\n     inkscape:window-height=\"449\"\n     inkscape:window-x=\"0\"\n     inkscape:window-y=\"25\"\n     inkscape:window-maximized=\"0\"\n     inkscape:current-layer=\"layer1\" />\n  <defs\n     id=\"defs1\" />\n  <g\n     inkscape:label=\"Layer 1\"\n     inkscape:groupmode=\"layer\"\n     id=\"layer1\">\n    <text\n       xml:space=\"preserve\"\n       style=\"font-size:43.4281px;fill:#00ff00;stroke-width:5.4285\"\n       x=\"28.561747\"\n       y=\"86.570786\"\n       id=\"text1\"\n       transform=\"scale(0.95191966,1.0505088)\"><tspan\n         sodipodi:role=\"line\"\n         id=\"tspan1\"\n         style=\"stroke-width:5.4285\"\n         x=\"28.561747\"\n         y=\"86.570786\">A bunch</tspan><tspan\n         sodipodi:role=\"line\"\n         style=\"stroke-width:5.4285\"\n         x=\"28.561747\"\n         y=\"140.85587\"\n         id=\"tspan2\">of text</tspan></text>\n  </g>\n</svg>\n"),
}

How to reproduce

1. Create an SVG image containing text using Inkscape.
2. Save file to program source directory as text.svg
3. fyne bundle -o bundled.go $GOPATH/source-dir/text.svg
4. go run .

Screenshots

Here is the image as created in Inkscape:

Using the program in the example code, below, this is what is displayed:

Example code

package main

import (
	"fyne.io/fyne/v2"
	"fyne.io/fyne/v2/app"
	"fyne.io/fyne/v2/canvas"
)

func main() {
	myApp := app.New()
	mainWin := myApp.NewWindow("image test")
	image := canvas.NewImageFromResource(resourceTextSvg)
	mainWin.SetContent(image)
	mainWin.Resize(fyne.NewSize(300, 300))
	mainWin.ShowAndRun()
}

You're right our SVG parser does not yet handle text.
