Describes flags that influence how the renderer interacts with a custom vertex shader.

Syntax

typedef enum D2D1_CHANGE_TYPE {
  D2D1_CHANGE_TYPE_NONE = 0,
  D2D1_CHANGE_TYPE_PROPERTIES = 1,
  D2D1_CHANGE_TYPE_CONTEXT = 2,
  D2D1_CHANGE_TYPE_GRAPH = 3,
  D2D1_CHANGE_TYPE_FORCE_DWORD = 0xffffffff
} ;

D2D1_CHANGE_TYPE_PROPERTIES Value: 1 The properties of the effect changed.
D2D1_CHANGE_TYPE_CONTEXT Value: 2 The context state changed.
D2D1_CHANGE_TYPE_GRAPH Value: 3 The effect’s transform graph has changed. This happens only when an effect supports a variable input count.
