forked from bartvdbraak/blender
95dcf11a88
implemented the support for animated colors and a workaround for non animated colors. To be cleaned if/when this bug is fixed: [#25487] BGE: Object Color only works when it has a keyed frame * also increased the size of the text. Now it supports 280 (or 140 unicode) chars.
