Subject: [PATCH] api: Fix printing of a size_t value

size_t is not always the same as long, especially not for 64 bit Windows:

api/pdfrenderer.cpp:549:31: warning:
 format '%ld' expects argument of type 'long int',
 but argument 4 has type 'size_t {aka long long unsigned int}' [-Wformat=]

size_t normally requires a format string "%zu", but this is unsupported
by Visual Studio, so use a type cast.
