Re: [dev] [Bug?] Incorrect font render size, dwm/ dmenu

Well this is weird, they are rendered at correct sizes now. I could swear i saw them being rendered bigger than the specified size. Perhaps i confused something.

Anyways, testing now i find them being rendered correctly. I'll be on lookout in case i come across the issue again. I had a screenshot which showed the relevant dwm/ dmenu config.h files and the mismatched rendering... which i sadly deleted before testing. But just for the record, these were the sizes that i had used:

// dwm
static const char *fonts[] = { "monospace:size=10.5" };
static const char dmenufont[] = "monospace:size=10.5";
// st
static char *font = "monospace:size=10.5";

If i was not confused/ mistaken then it's likely to be a bug in the relevant font libraries that the tools use. Of course other setup specific/ related factors could also be responsible.

The font(s) appear bigger than the specified 10.5pt size (compared with font rendering on `st`, which renders correctly, at the same size).
