/**
|
|
* This class provides a button that fixes several bugs present in the vanilla GuiButton drawing code.
|
|
* The gist of it is that it allows buttons of any size without gaps in the graphics and with the
|
|
* borders drawn properly. It also prevents button text from extending out of the sides of the button by
|
|
* trimming the end of the string and adding an ellipsis.<br/><br/>
|
|
*
|
|
* The code that handles drawing the button is in GuiUtils.
