word break cause by color tag

Issue details

the second draw of font should not break the word “international”. It just one word with different color.

Reproduction steps/code

	public void render(float delta) {
		Gdx.gl.glClearColor(0.6f, 0.6f, 0.6f, 1.0f);
		Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
		
		batch.setProjectionMatrix(camera.combined);

		shape.begin(ShapeRenderer.ShapeType.Line);
		shape.setColor(Color.RED);
		shape.rect(0, VIRTUAL_HEIGHT - 600, 300, 600);
		shape.end();

		batch.begin();
		font.getData().setScale(0.5f);
		font.draw(batch, "[BLUE]Is this a bug? international string123456789abcdefghiklmn",
				0.0f, VIRTUAL_HEIGHT,
				300.f, Align.left, true);
              // [output](http://pasteboard.co/OPDave7xa.png)
		font.draw(batch, "[BLUE]Is this a bug? inter[RED]national string123456789abcdefghiklmn",
				0.0f, VIRTUAL_HEIGHT - 200,

               // [output](http://pasteboard.co/OPuY5FCP6.png)
		batch.end();

Nah, I spent so much time already, I’m not going to resign.

I already abandoned the option we talked about above as it turned out to be really crazy because recursive linebreaks are needed where you have to keep track of all runs which are already dangling behind the one to wrap, etc. Not really a sane option, I tried it so I know. Or I just didn’t get it working correctly, also possible.

Whenever something is overly complicated I often remember that in these cases normally the underlying data structure or architecture is not suited to the problem to be solved. After looking at the whole thing the problem with the data structure here is that wrapping is mixed with color changes. I.e. lines are broken because of color changes. That’s the reason why wrapping is so complicated. There is a really cool way to solve this problem I’m working on right now which would require the GlyphRuns to change the color-change handling a little bit, the rest of the code would even be simplified a lot and still using the all the methods which are already in use. It’ll basically will be only one GlyphRun per line. If GlyphRun color handling is not to be touched this can also changed to create GlyphRuns as they are now with a little overhead.

When I’m finished, please test with your project if you notice any difference. Even if you guys do not like it I will still use it for my own project, as I’ll be using color-markup in many texts I guess.
