--- Comment #7 from V Stuart Foote <vstuart.foote at utsa.edu> ---
Issue remains, and seems we need to test for _WIN64 here and use the
'"gswin64c" EXESUFFIX,' for RenderAsBMPThroughHelper [1].

Things were complicated with a MS security change in handling of SYMLINKs
[2][3]

On 64-bit Windows we now have to make a hard link [4] creating gswin32c.exe
link to the 64-bit gswin64c.exe to be able to use Ghostscript to render the EPS
to canvas with RenderAsBMPThroughGS [5]

[4] That is:
1. navigate to bin directory of the 64-bit gs install, e.g. C:\Program
Files\gs\g9.21\bin

2. hard link with "mklink /h gswin32c.exe gswin64c.exe"

before a simple symlink with mklink sufficed, now have to use the hardlink.
