Detailed Description

win32 generic core window implementation.

Provides interface for core renderers to a win32 api client area.

This module is an object that must be encapsulated. Client users should embed a struct nsw32_corewindow at the beginning of their context for this display surface, fill in relevant data and then call nsw32_corewindow_init()

The win32 core window structure requires the callback for draw, key and mouse operations.
