Content Fit Feature for Evas_Object_Textblock
This Feature is available at Evas object level. And Edje level (where it is internally use evas functionality)
This feature will allow text block to fit its content font size to proper size to fit its area.
Fit Modes : None=Default, Width, Height, All [Width+Height]
Fit Size Range : Contains maximum and minimum font size to be used (and in between).
Fit Step Size : Step(Jump) value when trying fonts sizes between Size_Range max and min.
Fit Size Array : Other way to resize font, where you explicitly select font sizes to be uses (for example [20, 50, 100] it will try 3 sizes only)
Text Fit feature was available in Edje but:
1- It doesn't effected by ellipsis or warping in font style (or do not handle the in right way)
2- Accuracy is not good (specially if you have fix pixel size elements (spaces,tabs,items))
3- No (Step size, Size Array) available.
