Freetype and SharpFont FUSEE Build

This project contains the sources from the freetype project as well as those from the freetype C# wrapper project, SharpFont.

The goal is to deliver a working SharpFont/freetype package for each platform supported by FUSEE (currently Windows, MacOS and Android).

In addition to the SharpFont project, this project builds the underlying freetype dll from scratch instead of deploying a pre-built dll with the project. The main solution thus contains builds for Android (and iOS in the future) using Visual Studio 15's native code compiling features for mobile platforms.

Modifications applied to freetype

Updated freetype-2.6.2\builds\windows\vc2010\freetype.vcxproj to Visual Studio 15.
Copied project file to FreetypeFusee\FreetypeFusee.Windows\FuseeFreetype.Windows.vcproj
Applied SharpFont\Dependencies\freetype2\win64.patch to freetype
Changed the following project properties under -> General -> (for ALL CONFIGURATIONS AND ALL PLATFORMS)
- Configuration Type to "Dynamic Library (.dll)
- Changed output directory from ..\..\..\obj\VC2010\... to ..\..\..\..\bin\freetype\...
- Changed Intermediate Directory from ..\..\..\obj\VC2010\... to ..\..\..\..\tmp\...
Edited ftoption.h: definition of FT_EXPORT:

	#ifdef PLATFORM_WINDOWS
	#define FT_EXPORT(x)      __declspec(dllexport) x
	#define FT_EXPORT_DEF(x)  x
	#elif PLATFORM_ANDROID
	#endif

Remeved all Configurations (like Multithreaded) besides Debug and Relase
Moved all CLCompile and CLHeader .c and .h entries from FuseeFreetype.Windows.vcproj to FuseeFreetype.Shared.vcxitems besides ftdebug.c which directly addresses Windows.
Defined <FreetypeRoot>..\..\freetype-2.6.2\</FreetypeRoot> property in both, FuseeFreetype.Windows.vcproj and FuseeFreetype.Shared.vcxitems and replaced all relative paths with $(FreetypeRoot)
Copied ftdebug.c to FreetypeFusee\FreetypeFusee.Windows\
Fixed afwarp.h

  FT_LOCAL( void )
  af_warper_compute( AF_Warper      warper,
                     AF_GlyphHints  hints,
                     AF_Dimension   dim,
                     FT_Fixed      *a_scale,
	                 FT_Pos        *a_delta ); // !!! Replaced FT_Fixed with FT_Pos

Added additional projects referencing the shared FuseeFreetype.Shared.vcxitems sources for Android and iOS.

Modifications applied to SharpFont

FT.Internal.cs: changed FreetypeDLL:

		#if DEBUG 
		private const string FreetypeDll = "freetype262d.dll";
        #else
		private const string FreetypeDll = "freetype262.dll";
        #endif

SharpFont.dll.config: Renamed freetype6.dll to self-built dll:

	<dllmap dll="freetype262.dll">
		<dllentry os="linux" dll="libfreetype.so.6" />
		<dllentry os="osx" dll="/Library/Frameworks/Mono.framework/Libraries/libfreetype.6.dylib" />
	</dllmap>
  <dllmap dll="freetype262d.dll">
    <dllentry os="linux" dll="libfreetype.so.6" />
    <dllentry os="osx" dll="/Library/Frameworks/Mono.framework/Libraries/libfreetype.6.dylib" />
  </dllmap>

Changed output directory to {projectroot}\bin\SharpFont\...
Removed reference to System.Drawing and commented out using System.Drawing;, FTBitmap.ToGdiBitmap() and FTBitmap.ToGdiBitmap(Color color) in FTBitmap.cs.

Modifications applied to Examples

Changed the content items x86\freetype6.dll and x64\freetype6.dll in the .csproj file to the respective freetype262.dlls including debug build distinction (freetype262d.dll).
Added speceific x86 and x64 platform builds (in addition to the AnyCPU platform) to explicitly test both platforms on Windows.
Changed output directory to {projectroot}\bin\SharpFontExample\...

Usage in FUSEE

FUSEE uses the libraries built within this project by keeping copies under {FuseeRoot}\ext\SharpFont\bin\....
