Feature/slide background

[thomasowow]

Fixes #533

Adds the feature to add a background image to a slide which is not a master.

Use:

// The parameter can be exactly the same as one for a [master slide](https://gitbrent.github.io/PptxGenJS/docs/masters.html).
slide.background({
    src: 'some-url',
});

Hey @gitbrent - any chance this could be reviewed? Would be super handy.

Given the pull request is against the dist files, rather than the source, this pull request won't be merged. @thomasowow - the project has had a number of changes since this pull request was made, it's not immediately obvious where your code ought to go, but it might be worth opening a new PR?

Thanks @thomasowow

Code is too old to merge, so i've added it manually.

Add a background image to any slide now:

slide.background = {
  path: "https://raw.githubusercontent.com/gitbrent/PptxGenJS/master/demos/common/images/starlabs_bkgd.jpg"
}

@gitbrent I tried testing this (locally build from latest commit 7ae0765) and it's not working.

I tried to add a background image like this:

slide.background = { path: "https://raw.githubusercontent.com/gitbrent/PptxGenJS/master/demos/common/images/starlabs_bkgd.jpg" }

Am I doing something wrong?

@gnikolovski

Make sure your version shows 3.3.0-beta

var pptx = new PptxGenJS();
var slide = pptx.addSlide();

slide.background = {path:'https://raw.githubusercontent.com/gitbrent/PptxGenJS/master/demos/common/images/starlabs_bkgd.jpg'}

slide.addText('background!', { x:1, y:1, w:'80%', h:1, align:'center', fill:pptx.SchemeColor.background2 });

pptx.writeFile('PptxGenJS-Test');
