Addendum to 60ae4c3 (experimental fix)

The problem is that tocolor(255,255,255) returns -1.0d, but dxDrawText reads an uint, so it relies on unclean conversion from double to uint.
Instead, tocolor should return (lua_Number)0xffffffff instead of (lua_Number)(int)0xffffffff

Also, lua_pushinteger(l, int n) is basically lua_pushnumber(l, (lua_Number)n) so the unsigned information is just lost here.
This commit might cause side effects though as there may be scripts that rely on tocolor returning -1 for 0xffffffff/white
