FontPackParams::SetUseSeparateTextures

void SetUseSeparateTextures(bool flag);

SetUseSeparateTextures sets the flag of using separate textures for each font and can be retrieved by GetUseSeparateTextures. 

Sometimes it is desirable to use separate textures for each font. In case of limited set of fonts and glyphs it may reduce the resulting number of draw primitives, but it increases the number of textures and decreases the density of packing.
