/* If your system embeds skia and has complex event logging, in
src/config/SkUserConfig.h:
- define the three SK_TRACE_EVENT macros to map to your system's
equivalents,
- define the name of the include file in SK_USER_TRACE_INCLUDE_FILE
A trivial example is given in src/utils/SkDebugTrace.h.
All arguments are const char*. Skia typically passes the name of
the object and function (and sometimes region of interest within
the function) separated by double colons for 'event'.
SK_TRACE_EVENT1 and SK_TRACE_EVENT2 take one or two arbitrary
name-value pairs that you also want to log. SkStringPrintf() is useful
for formatting these values.
For example:
SK_TRACE_EVENT0("GrContext::createAndLockTexture");
SK_TRACE_EVENT1("GrDefaultPathRenderer::onDrawPath::renderPasses",
"verts", SkStringPrintf("%i", vert - base).c_str());
