icons - TVG Icons Ready to use in Zig

icon libraries included:

usage (in dvui):

const icons = @import("icons")

const Wrapper = struct {
 width: i64,
 height: i64,
 img: *MyImage,
 pub fn setPixel(self: *@This(), x: i64, y: i64, color: [4]u8) void {
 const pix: MyPixel = .init_from_u8_slice(&color);
 self.img.set_pixel(@intCast(x), @intCast(y), pix);
 }
};
const width_and_height = 200;
var myImage = try MyImageType.init(alloc, width_and_height, width_and_height);
const my_svg_icon_data = icons.svg.feather.activity;
var w = std.ArrayList(u8).init(alloc);
try svg2tvg.tvg_from_svg(alloc, w.writer(), svg_bytes);
var image_wrapper = Wrapper{
 .img = img,
 .width = @intCast(img.get_width()),
 .height = @intCast(img.get_height()),
};
var fb = std.io.fixedBufferStream(w.items);
try svg2tvg.renderStream(alloc, &image_wrapper, fb.reader(), .{});
