* claim: #1801 * Insert SVG: the file picker opens on SVG files (#1801) Every Open went through one host picker whose filters start with designs, CAD files and meshes, so Insert SVG (and Insert DXF) in a sketch opened on STEP, IGES and meshes, and the SVG file had to be found under another filter. The host's pick_open now takes the extensions the command reads and offers them as the picker's first, default filter. Insert SVG and Insert DXF pass their type; every other Open passes none and keeps the list it had. The browser host ignores them (it shows its own file panel). --------- Co-authored-by: MateuszSychXpl <151755914+MateuszSychXpl@users.noreply.github.com>
