Description:
Calc can export SVG images, which are useful when a graph contains lots of information and ie. font size 6 is used to show labels and in X/Y-axes. Often much better format to use when exporting graph-images from the Calc, and later imported to PDF-document. Smooth and sharp unlimited zooming is useful.

But since SVG images are XML, they are well (lossless) compressible to SVGZ format.

(I saw some support for reading SVGZ files as a batch in bug #75487 but it didn't mention support for export and at least in LO which comes in Fedora 34 [v.7.1.6.2.0] exporting SVGZ from Calc seems not to be possible.)

Steps to Reproduce:
1. Make a graph in LO Calc. Use font size 5 or 6 in labels.
2. Use mouse 2nd button over the graph and take Export As Image
3. Choose format SVG in bottom right where format is chosen. See there is no SVGZ
4. Save the image as SVG.




Actual Results:
5. Check with Notepad or with hexeditor or with CLI less, the SVG file is uncompressed XML file.

Expected Results:
Be able to select SVGZ as a image format in stage 3, and have compressed SVGZ image file exported.
