Subject: [PATCH 08/16] patch 8.0.1384: not enough quickfix help; confusing
 winid

Problem:    Not enough quickfix help; confusing winid.
Solution:   Add more examples in the help. When the quickfix window is not
            present, return zero for getqflist() with 'winid'. Add more tests
            for jumping to quickfix list entries. (Yegappan Lakshmanan, closes
            #2427)

Subject: [PATCH 12/16] patch 8.0.1388: char not overwritten with ambiguous
 width char

Problem:    Char not overwritten with ambiguous width char, if the ambiguous
            char is single width but we reserve double-width space.
Solution:   First clear the screen cells. (Ozaki Kiichi, closes #2436)

Subject: [PATCH 13/16] patch 8.0.1389: getqflist() items are missing if not
 set

Problem:    getqflist() items are missing if not set, that makes it more
            difficult to handle the values.
Solution:   When a value is not available return zero or another invalid
            value. (Yegappan Lakshmanan, closes #2430)

Subject: [PATCH 14/16] patch 8.0.1390: DirectX scrolling can be slow, vertical
 positioning is off

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
