Summary: When using CSS-Layout in a C# UWP project in x86, by default the MSVC compiler defaults the delegate calling convention to cdecl, while .NET assumes that all delegates are declared using stdcall. This causes a problem when invoking such as this error: ``` Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call. This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention. ``` This PR changes the calling convention in the C# code to reflect cdecl by using the `UnmanagedFunctionPointer` attribute and setting the calling convention to `CallingConvention.Cdecl`. ```csharp [UnmanagedFunctionPointer(CallingConvention.Cdecl)] public delegate CSSSize CSSMeasureFunc( IntPtr context, float width, CSSMeasureMode widthMode, float height, CSSMeasureMode heightMode); ``` I have updated all calls as well to other functions.
