patch 8.0.1390: DirectX scrolling can be slow, vertical positioning is off

Browse Source 
Problem:    DirectX scrolling can be slow, vertical positioning is off.
Solution:   Make scroll slightly faster when using "scrlines:1". Fix y
            position of displayed text. Fix DirectX with non-utf8 encoding.
            (Ken Takata, closes #2440)

14. Building with DirectX (DirectWrite) support
===============================================
Vim with DirectX (DirectWrite) support can be built with either MSVC or MinGW.
This requires dwrite_2.h and some other header files which come with Windows
SDK 8.1 or later (or MinGW-w64), if you want to enable color emoji support.
This also requires MBYTE=yes which is enabled by default.
A) Using MSVC
If you use MSVC 2013 or later, Windows SDK 8.1 or later is used by default.
You just need to specify DIRECTX=yes:
nmake -f Make_mvc.mak DIRECTX=yes
If you use MSVC 2012 or earlier, the required header files are not available
by default. However, you can use the header files from newer SDKs with older
compilers. E.g.:
set "INCLUDE=%INCLUDE%;C:\Program Files (x86)\Windows Kits\8.1\Include\um"
nmake -f Make_mvc.mak DIRECTX=yes
If you don't need color emoji support, only dwrite.h is required. You can use
older compilers (e.g. VC2010) without Windows SDK 8.1. E.g.:
nmake -f Make_mvc.mak DIRECTX=yes COLOR_EMOJI=no
B) Using MinGW-w64
Just set DIRECTX to yes:
mingw32-make -f Make_ming.mak DIRECTX=yes
15. Windows 3.1x
================
The Windows 3.1x support was removed in patch 7.4.1364.
15. MS-DOS
16. MS-DOS
==========
The MS-DOS support was removed in patch 7.4.1399. Only very old Vim versions
work on MS-DOS because of the limited amount of memory available.
