What is technical art behind “Skia Enabled” old app? about skia4delphi HOT 3 OPEN

Skia4Delphi is a graphics library that can be seen in 3 main parts: api, controls and fmx renderer. "Enable Skia" will set binaries and configure deployment in your project (as we are still a shared library), and is a fundamental step towards using the library. The fmx renderer is an extra and optional feature, being enabled by adding ::Fmx::Skia::GlobalUseSkia = true; at program startup (in Delphi, this line is automatically added to the .dpr when clicking "Enable Skia"). After that, skia4delphi will register its own TCanvas for forms, bitmaps and printers. Skia does not support 3D drawings, so it does not replace the rendering of 3D forms (TContext3D), but this is changing in newer versions and perhaps we will have a 3D rendering based on Skia in the future.

In addition, there are some backends of Skia that can be chosen, in special, the Vulkan (that is still disabled by default).

The fmx renderer is an extra and optional feature, being enabled by adding ::Fmx::Skia::GlobalUseSkia = true; at program startup

1. Click on your project, then Ctrl + V (to open the source;
2. Add the code to enable Skia Vulkan render:

//---------------------------------------------------------------------------

#include <fmx.h>
#ifdef _WIN32
#include <tchar.h>
#endif
#pragma hdrstop
#include <System.StartUpCopy.hpp>
#include <FMX.Skia.hpp>
//---------------------------------------------------------------------------
USEFORM("Unit1.cpp", Form1);
//---------------------------------------------------------------------------
extern "C" int FMXmain()
{
	try
	{
		// Allowing Skia to replace the app render by Skia Vulkan
		::Fmx::Types::GlobalUseVulkan = true;
		::Fmx::Skia::GlobalUseSkiaRasterWhenAvailable = false;
		::Fmx::Skia::GlobalUseSkia = true;

		Application->Initialize();
                ...

Thank you. Just a recommendation, a schematic graphical pipeline presentation (one side old FMX app, other side skia enabled FMX app) would be nice to explain all, thank you. i.e. https://vulkan-tutorial.com/Drawing_a_triangle/Graphics_pipeline_basics/Introduction
