2017-12-03ALL: Remove obsolete register keywordColin Snover
The register keyword was deprecated from the C++11 standard, <http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2014/n4193.html#809>, and removed from the C++17 standard, <http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2015/n4340>, so cannot exist in a well-formed C++17 program. It has never done anything in GCC <https://gcc.gnu.org/ml/gcc/2010-05/msg00113.html> and because of the way it is specified in the standard, it is “as meaningful as whitespace” <http://www.drdobbs.com/keywords-that-arent-or-comments-by-anoth/184403859>. The one remaining use of the register keyword is in the DS backend, where it is used to create a local register variable using the non-standard GCC Extended Asm feature. Closes gh-1079.

2017-11-18COMMON: Add limited support for custom deleters to ScopedPtrColin Snover
Custom deleters of ScopedPtr are not currently fully conforming to C++11's support for custom deleters in std::unique_ptr for the sake of simplicity of implementation. Unlike in the standard library, plain functions and lvalue references are not supported, nor may custom deleters be passed to the constructor at runtime. This can be improved in the future, if necessary, by doing what standard library implementations usually do and creating a Pair class that uses the Empty Base Optimization idiom to avoid extra storage overhead of the deleter instance when it is not needed, as in typical standard library implementations, plus some additional type traits to support the necessary metaprogramming for the different type overloads.

Blank cursors don't mean to continue drawing the previous cursor, they mean that the cursor in the backend needs to be blank.
2017-10-15BACKENDS: Refactor OpenGL & SDL graphics backendsColin Snover
This patch refactors the OpenGL and SDL graphics backends, primarily to unify window scaling and mouse handling, and to fix coordinate mapping between the ScummVM window and the virtual game screen when they have different aspect ratios. Unified code for these two backends has been moved to a new header-only WindowedGraphicsManager class, so named because it contains code for managing graphics managers that interact with a windowing system and render virtual screens within a larger physical content window. The biggest behavioral change here is with the coordinate system mapping: Previously, mouse offsets were converted by mapping the whole space within the window as input to the virtual game screen without maintaining aspect ratio. This was done to prevent 'stickiness' when the mouse cursor was within the window but outside of the virtual game screen, but it caused noticeable distortion of mouse movement speed on the axis with blank space. Instead of introducing mouse speed distortion to prevent stickiness, this patch changes coordinate transformation to show the system cursor when the mouse moves outside of the virtual game screen when mouse grab is off, or by holding the mouse inside the virtual game screen (instead of the entire window) when mouse grab is on. This patch also improves some other properties of the GraphicsManager/PaletteManager interfaces: * Nullipotent operations (getWidth, getHeight, etc.) of the PaletteManager/GraphicsManager interfaces are now const * Methods marked `virtual` but not inherited by any subclass have been de-virtualized * Extra unnecessary calculations of hardware height in SurfaceSdlGraphicsManager have been removed * Methods have been renamed where appropriate for clarity (setWindowSize -> handleResize, etc.) * C++11 support improved with `override` specifier added on overridden virtual methods in subclasses (primarily to avoid myself accidentally creating new methods in the subclasses by changing types/names during refactoring) Additional refactoring can and should be done at some point to continue to deduplicate code between the OpenGL and SDL backends. Since the primary goal here was to improve the coordinate mapping, full refactoring of these backends was not completed here.
