branch: master
commit 324612ceb24d97563a88415ebc84b3dcb3b935f0
Author: Werner Lemberg <wl@gnu.org>
Commit: Werner Lemberg <wl@gnu.org>
Always provide logging API.
It's easier to have stubs if FT_DEBUG_LOGGING is undefined than to
modify `ftexport.sym` conditionally.
Problem reported by Alexei.
* src/base/ftdebug.c: Include `ftlogging.h`.
(FT_Trace_Set_Level, FT_Trace_Set_Default_Level, FT_Set_Log_Handler,
FT_Set_Default_Log_Handler) [!FT_DEBUG_LOGGING]: Provide stubs.

If `FT_DEBUG_LOGGING' is defined, four APIs are available to provide
