* Add MakeRectangle helper to convert from SDL_Rect
* Add Rectangle::inset method for shrinking a rectangle
Turns out some of the other use cases I though this could apply to were actually doing something based on a fixed region
* Simplify initialisation of settings menu rects
The backgrounds can be quite large, for example
the Hellfire title background is a 2.4 MiB PCX file.
Previously, we converted all background to SDL surfaces.
This required extra memory, e.g. the 2.4 MiB Hellfire
title background uses 4.6 MiB as an SDL surface.
Changes the background to render directly from PCX instead
to reduce the allocator pressure.
Introduces a `ControlDevice` global which is distinct from `ControlMode`
in that it is set to `Gamepad` even when simulating a mouse.
This allows us to avoid a number of edge cases related to mode changes.
Fixes#4242
Hardware cursor should get initialized even for non mouse control types
(e.g. `ControlTypes::None`), because by the time the control type gets
initialized or changes the cursor is already set up and won't change.
Fixes#4233
The gamepad cursor (inventory, spells etc) no longer relies on warping a
real mouse cursor. This should make things work better on platforms that
do not support this, like Wayland.
libmpq is a much simpler alternative to StormLib for reading MPQ archives.
We use our own fork of libmpq: https://github.com/diasurgical/libmpq
Impact:
* DevilutionX is now a lot more portable. Unlike StormLib, libmpq only
needs platform-specific code for Windows.
* Locks around file access **removed** (instead we duplicate the file descriptor for streamed audio only).
* RAM usage is **300 KiB** lower than StormLib.
* Stripped release linux_x86_64 binary is **32 KiB** smaller.
* Amiga build now hangs instead of crashing.
Double clicking a menu list was not intuitive and could leave some
people confused about how to progress from the very first screen.
This is unfortunatly more important then having a nice preview when
using arrow keys to high light the other option :(
