This is a doxygen review for 4 header files that have been
identified as high priority for GSoD:
- advancedDetector.h
- metaengine.h
- engine.h
- util.h
It also adds doxy groups to other headers from this folder to
make them appear properly in the structure.
Enabled system API for begin/end gfx transactions, initSize, setGraphicsMode.
Function setGraphicsMode will use optional params to trigger 3d rendering
and switch to proper SDL Gfx manager.
This flag is removed for a few reasons:
* Engines universally set this flag to true for widths > 320,
which made it redundant everywhere;
* This flag functioned primarily as a "force 1x scaler" flag,
since its behaviour was almost completely undocumented and users
would need to figure out that they'd need an explicit non-default
scaler set to get a scaler to operate at widths > 320;
* (Most importantly) engines should not be in the business of
deciding how the backend may choose to render its virtual screen.
The choice of rendering behaviour belongs to the user, and the
backend, in that order.
A nearby future commit restores the default1x scaler behaviour in
the SDL backend code for the moment, but in the future it is my
hope that there will be a better configuration UI to allow users
to specify how they want scaling to work for high resolutions.
These functions are only used internally be Engine subclasses, and
by moving them to a separate header we can reduce indirect header
dependencies.
