commit d74440a327d6437b5eecd7d552576dbf22e12028
Author: Alexei Podtelezhnikov <address@hidden>
Commit: Alexei Podtelezhnikov <address@hidden>
[base] Improve tracing in FT_Load_Glyph, FT_*_Size.
* src/base/ftobjs.c (FT_Load_Glyph): Tag tracing messages with
function name, glyph index, and load flags.
(FT_Select_Metrics, FT_Request_Metrics): Remove all tracing.
(FT_Select_Size, FT_Request_Size): Improve tracing.
