[1.19.4] Alternatives to ItemRenderer.renderGuiItem(), .renderAndDecorateFakeItem() and .blitOffset ?

Hi all,

I think the title says it all. I was using the ItemRenderer.renderGuiItem(), .renderAndDecorateFakeItem() and .blitOffset methods/properties on my mod for 1.18.2, but whilst trying to update to 1.19.4 I realized that they were no longer available, nor could I find any suitable replacements.

If necessary, here is how I was using each method:

- .renderGuiItem() and .blitOffset were to render fake items inside a Button subclass:

//Draw item
        if(item.isItem()) {
            itemRenderer.renderGuiItem(item.getItem(), x, y);
        }

        //Highlight background and write item name if hovered or focused
        if(isHoveredOrFocused()){
            isMouseOn = true;
            fill(matrix, x, y, x+width, y+height, 0xFFFFFFDF);
        }else{
            isMouseOn = false;
        }

        //Write quantity based on buttons pressed (sneak & run)
        matrix.pushPose();
        matrix.translate(0, 0, itemRenderer.blitOffset+201);
        matrix.scale(.5f, .5f, 1);
        Font font = Minecraft.getInstance().font;
        drawString(matrix, font, getQuantity()+"", 2*(x+16)- font.width(getQuantity()+""), 2*(y)+24, 0xFFFFFF);
        if(item.isTag()){
            drawString(matrix, font, "#", 2*x+width*2-font.width("#")-1, 2*y+1, 0xFFC921);
        }else if(!item.isItem()){
            drawString(matrix, font, "F", 2*x+1, 2*y+1, 0x6666FF);
        }

- .renderAndDecorateFakeItem() was used to render a fake item inside a Screen subclass:

private void renderItem(PoseStack matrixStack, Item item, int x, int y) {
        ItemRenderer itemRenderer = this.minecraft.getItemRenderer();
        ItemStack itemStack = new ItemStack(item);
        itemRenderer.renderAndDecorateFakeItem(itemStack, x, y);
    }

Which are the alternatives for 1.19.4?
