Backports the text rendering code from 1.6 to 1.5.
Done by starting with the current master's engine/render/text_render
and backporting things as-needed until it worked.
CLX rendering and text input handling are also backported as part of
this change.
This is much faster in debug mode than the non-C++17 version.
For example, with timedemo_test in debug mode, `M_Talker` goes from 11%
of the total time to just 3.5%.
* 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.
