Regression since 3.12 : text from a BMFont is moved a few pixels to the right.

[Paco777]

• cocos2d-x version: 3.13.1
• devices test on: iPhone6
• developing environments : Xcode version: 8.1

Steps to Reproduce:

1. create and display a label from a BMFont :
   Label::createWithBMFont("font_numbers.fnt","2", TextHAlignment::CENTER);

2. In 3.13.1, the text is offset in x of a few pixels (and is partly outside the smaller bounding box)
   The problem was not in my previous 3.12 version.
   This is annoying if the try to center the text.

Attached a screenshot of the same code running on 3.12 and 3.13.1.

Could you upload font_numbers.fnt, the background picture and more code snippets?

Here is the adapted HelloWorldScene.cpp and the 2 new font resource files than can be added in an HelloWorld sample code generated by Cocos2D-x :
FontPb.zip

Here are the screenshots of the execution :
in 3.12 :

3.13.1 :

I found that it's this PR (#16172) broke it.
@minggo , any thought about this?

[dumganhar]

@Paco777, you could revert the change in https://github.com/cocos2d/cocos2d-x/pull/16172/files to fix this issue temporarily.

@dumganhar thanks a lot, I will !
And thanks to all the cocos team for this great library and support.

Hi,
the problem is still there in 3.14.1.
But your workaround to temporarily fix this issue is still working.
