Javadoc
Sets the maximum size that will be used when generating texture atlases for glyphs with generateData(). The
default is 1024. By specifying
#NO_MAXIMUM, the texture atlas will scale as needed.
The power-of-two square texture size will be capped to the given texSize. It's recommended that a power-of-two
value be used here.
Multiple pages may be used to fit all the generated glyphs. You can query the resulting number of pages by calling
bitmapFont.getRegions().length or freeTypeBitmapFontData.getTextureRegions().length.
If PixmapPacker is specified when calling generateData, this parameter is ignored.
