Add attribute to limit the canvas-height to its container

[lesteenman]

This patch adds an attribute that, combined with scale='page-fit',
allows to fit the contents inside of the page both with respects to the
width and with respect to the height. Think of it as using
background-size='contain' rather than the default behavior of
background-size='cover' that scale='page-fit' triggers.

Fixes #127.

WIP: Pushed too early.

Note: It seems that even the cleanly pulled branch does not pass the tests, with the same error I'm getting here. However, I see that Travis still says your own builds are passing. Am I doing something wrong?

Thanks @lesteenman - I haven't look at this in detail, but could you see some instructions on CONTRIBUTING.md to run some tests / build locally with grunt and npm? That might give you some clue hopefully!

[lesteenman]

Yes, I have. I'm having no issues with steps 1-4. However, when I run npm run build, I'm getting the following error:

Running "karma:unit" (karma) task

Note that this same error occurs with a clean clone of your repository, and the same error occurs with the Travis CI build. Running npm test also gives this error.

[lesteenman]

Updating karma-phantomjs-launcher to ^1.0.0 (from ^0.2.1) seems to have worked. I'll submit a new PR.

[lesteenman]

This new version does not include phantomjs-prebuilt anymore. Adding a commit to include this dependency manually.

[dennybiasiolli]

@lesteenman can you please rebase this PR? Now the problems with tests should be resolved.

[lesteenman]

The earliest I can do that is next Tuesday, probably. If there is a deadline before then, please do so yourself; the changes should be straightforward.

[dennybiasiolli]

Please apply changes to src/angular-pdf.js instead of dist/angular-pdf.js, then commit only that file with readme.md and some tests/examples
