This fixes the irregular dark fringes around light text when not exactly pixel-aligned that are caused by independent interpolation of color and alpha. It also makes calculations simpler for things to come.
In addition to being a prerequisite for shadowed text, this also fixes an issue sometimes seen at the bottom of the mini KI player list where characters with a descender were missing.
_PyTuple_Resize may destroy the original tuple and return a new one through the pointer argument. When it does that and we don?t put the new one back into the map, we end up with a stale pointer to a destroyed object in the map, which is likely to blow up one way or another next time it?s accessed.
Untested because, as far as I can see, this code isn?t actually used currently. All uses of this method deal with fixed-size SDL variables. Resizable variables are not used at all in age SDL, only in non-age SDL (animation, avatar, clothing etc.), and I?m not even sure if those are even accessible using this Python API.
Fixes egg room private chat channels and entering Teledahn buckets with Python 2.7. These and other uses of ptSDL.setIndex() only worked by chance with Python 2.3 because the tuples happened to have reference counts of 1.
