Add text tool

[ClFeSc]

Closes #35

[ClFeSc]

The test testSimpleText is known to fail. This will be fixed.

Without having looked at the code yet, UiFugueIcons >> editIcon seems like a more fitting icon for the text tool.

[kpostnov]

I don't know if it's just me but, in comparison to other branches, something is affecting the performance while drawing. Might be something to take a closer look at.

We currently have the problem that, when moving MorphicMonet, one can see the temporaryTextMorph floating around in the Image, approx. -100 asPoint away from the top left corner of the Canvas.

We currently have the problem that, when moving MorphicMonet, one can see the temporaryTextMorph floating around in the Image, approx. -100 asPoint away from the top left corner of the Canvas.

This temporary placement at -100 asPoint looks a bit tacky to me. Isn't there another way of hiding the morph at the beginning and between (for example deleting it and only creating it if used)?

[kpostnov]

When clicking the Choose Font - button while having the text tool activated it is possible to draw on the canvas even though only writing text should be allowed.

Should be fixed.

This one is being set twice. Once in the sender of dismissCurrent and once here. I suggest removing this line.

[ClFeSc]

I'd suggest removing it in the sender since we are also setting the focus in M2TemporaryTextMorph>>getAt:, so I think the same class should be responsible for releasing the focus.

[maximilian-franz]

I don't quite get the need for M2TemporaryTextMorph, what is the benefit of having such a temporary text morph, moving it to the target position and eventually creating a new Textmorph to print the text over simply creating a TextMorph at the target position and printing its contents?

[maximilian-franz]

getAt: sounds weird to me since the morph already exists. Maybe use moveTo: instead?
