pgAdmin 4 v1.0: Problems with high dpi scaling on Win10

lang="EN-US"> </span><pclass="MsoNormal"><span lang="EN-US">On Windows 10 using a high res screen with high dpi scaling
turnedon and set to 200%, the text in the pgAdmin 4 (standalone) interface becomes almost illegible. </span><p
class="MsoNormal"><spanlang="EN-US"> </span><p class="MsoNormal"><span lang="EN-US">The issue seems to be that pgAdmin
claimsto Windows that is high dpi aware when it actually isn’t. See <a

highdpi issues. </span><p class="MsoNormal"><span lang="EN-US"> </span><p class="MsoNormal"><span lang="EN-US">The
shortterm solution would be to make the app dpi unaware, thus letting Windows take care of the scaling. </span><p
