Same as IM_MEMALIGN(). 'alignment' must be a power of two.

ImFontBaked pointers are valid for the entire frame but shall never be kept between frames.

References are only valid until a new value is added to the storage. Calling a Set***() function or a Get***Ref() function invalidates the pointer.

Was tempted to lazily init FontSrc but wouldn't save much + makes it more complicated to detect invalid data at AddFont()

Glut has one function for characters and one for "special keys". We map the characters in the 0..255 range and the keys above.
