Incomplete C header information in gir for gdk-pixbuf.
Submitted by Tomasz Miąsko @tmiasko
Link to original bug (#793990)
Description
The gir data for gdk-pixbuf describes types and functions from gdk-pixbuf/gdk-pixdata.h header but doesn't include appropriate header either directly or indirectly.
Please change it so that information about C headers in gir is complete, by either: passing --c-include=gdk-pixbuf/gdk-pixdata.h to g-ir-scanner, or including gdk-pixdata.h along with the main header. Whichever you feel is more appropriate. Otherwise consumers of gir data that use it to generate C code have to write manual workarounds.
