* Add helper to test if an object is a trap source
* Add helper to test if an object is a barrel
* Add helper to test if an object is a crucifix
* Add helpers to check if an object is a chest (and statuses)
* Add helpers to check if an object is a (basic) shrine
* Update random number functions to avoid IB
Most calls to set seed were using uint32_t already, there were a few variables which were better served by having their type changed from signed to unsigned. The one exception is ItemStruct::_iSeed. This is an identifier that also happens to be used as a seed occasionally so a comment was added documenting this exception.
Includes suggested style changes for Source/towners.h; Source/towners.cpp; Source/msg.h; Source/multi.h
This documents the chosen LCG parameters and the default mapping function used in random number generation.
GetLCGEngineState() is a helper needed for testing because AdvanceRndSeed combines a distribution with a call to progress the engine. I'll split those eventually but this at least shows the current behaviour and should flag any bugs introduced by future changes.
1. Move `SetPixel` definition to the header to make it easier for the
compiler to inline (make it inlinable even without LTO).
2. Add an `operator[](Point)` overload to `CelOutputBuffer`.
Uses integer math only: This speeds up the rendering and eliminates some
zoom artifacts.
Improves player indicator look -- it's now symmetric and more legible.
Tthis gives us the option to specify what type a file should be loaded
as, avoidng the need to case it and does some automatic checks on the
fitness of the data, while making the process simpler.
If no type is given then the type will be set to std::byte which limit
what operations can be performed on the data.
