cucumber merge, multiline font object:
revisions: 38384,38387,38403,38404,38407,42997,42998
#42998 by dfelinto
BGE Font Object - fix for offset
(scaling also has to be taken into account here)
#42997 by dfelinto
Font Object Multiline fix.
The offset was totally wrong when object had scale[1] != 1
#38407 by kupoman
Changing the "text" property of a KX_FontObject now changes the text. This allows for control of a FontObject through logic bricks.
#38404 by kupoman
KX_FontObject now supports the x and y offset options.
#38403 by kupoman
KX_FontObject now makes use of the font's line spacing option, and correctly accounts for rotation and font size when applying the spacing.
#38387 by kupoman
The KX_FontObject text attribute is working again.
#38384 by kupoman
Primitive support for the new line character added to KX_FontObjects. The line spacing is fixed, and does not work when the FontObject is rotated. Also, the text attribute has been temporarily disabled, as it needs some updating to support the multiline changes.
