Text doesn't render anymore

Wr-sample doesn't render text anymore on current Wr.

Changes made can be seen in this commit.

Summary:
Delete Cargo.lock, Update src to fit trait requirements, compile on current nightly, reactivate text rendering - run and miss the text on the screen.

It's probably related to the Wr2 changes, the last commit which i got to compile on my machine and worked was this one.
The oldest non working which compiled is the one fixing the border fragment shader.

I'm going to dissect this problem further, but it seems to be a Wr related issue, so i'll post this in Wr.

What was the eventual issue? Should this be closed now?

The TextBoundaries are invalid.
If you give draw a glyph at (100,100), the corresponding bitmap lower left corner will be drawn at (100,100) (simplified, wr does take baseline into account). Therefore the bitmap upper right corner will be at the upper right, let's say (150,50).

But the boundaries start at (100,200) and has a size of (700,300). It simply doesn't contain the to be rendered glyph and i assume that Wr2 finally takes the bounds into account. Quick sketch:

Window:
$ Represents the to be rendered glyph, # the text boundaries
|==========|
| $        |
|          |
| #######  |
| #     #  |
| #######  |

I can make a PR for the fix (one number) if you'd like. But i would update the example to use the most current webrender as well.

The text works on 0.7.0 master (a3adb113f)! Discovered this while working on running Webrender on FreeBSD.

(However, if you just uncommented the text lines, the sample would crash FreeBSD out of the box, because the font path is /usr/local/share/fonts/dejavu/DejaVuSansMono.ttf here :D I think you should just commit a small font to the repo.)
