// This extracts all of the color cursors from a resource file and converts them to
|
||||
// Windows cursor format.
|
||||
//
|
||||
// Windows only supports loading color cursors by loading them from an executable or DLL resource,
|
||||
// or by loading them from a file, so we can't just do the conversion/construction at runtime.
|
||||
//
|
||||
// Also, classic Mac cursor features are not fully supported by newer operating systems.
|
||||
// The classic Mac cursor function is basically (existing ^ color) where the mask bit isn't set,
|
||||
// so it supports inversion masking and colors with the same cursor.
|
||||
//
|
||||
// Fortunately, none of the Glider PRO cursors use this combination.
|
||||
//
|
||||
// The color cursor format is not fully documented. Appears to be:
|
||||
// Header
|
||||
// CursorPixMapPrefix (at pixMapOffset)
|

// BEPixMap
|
||||
// Pixel data
|

// BEColorTableHeader
