This file has a list of functionality not yet implemented or issues that
have to be fixed in libgdiplus.
---- Functionality not implemented

- EXIF. There is libexif
- WMF and EMF. We do not support metafiles. See libwmf.
- ICON. Some icon functionality is done at SD level.
---- Not implemented functions

Functions that use or create Win32 handles and are not yet implemented
(except for window and device needed in System.Windows.Forms.)

* Pens and brushes
GdipSetPenDashCap197819
GdipGetPenDashCap197819
GdipSetPenCustomStartCap

* Functions releated to paths
GdipAddString
GdipAddStringI
GdipWindingModeOutline
GdipWidenPath
GdipWarpPath
---- Issues
* All the functions that create Cairo resources have to be review to make
sure that we do not over reference the handles. For example, calling
cairo_create and cairo_reference will set the internal cairo reference count
to two. A single cairo_destroy will decrease the internal counter to 1 but
it will not release the resource.
We have to review these calls to make sure that we are releasing propertly
the handles and not leaving them created when their associated object
(GpGraphics in this case) is destroyed.
* There are internal libgdiplus memory leaks. At general.c there is a little
DEBUG_MEMLEAKS define that enables an internal system to track down these
issues. Leave it always on and try to fix the leaks to you detect.
