While on the topic, I would like to implement function XRecolorCursor.
It seems simple to do.
Any reasons against it?
What would be the easiest way to change foreground/background color of a cursor in microwindows?

The description is:
Synopsis:
XRecolorCursor(display, cursor, foreground_color, background_color)
Display *display;
Cursor cursor;
XColor *foreground_color, *background_color;
Arguments:
display Specifies a connection to an X server; returned from XOpenDisplay().
cursor: Specifies the cursor ID.
foreground_color: Specifies the red, green, and blue (RGB) values for the foreground.
background_color: Specifies the red, green, and blue (RGB) values for the background.
Description:
XRecolorCursor() applies a foreground and background color to a cursor. Cursors are normally created using a single plane pixmap, composed of 0's and 1's, with one pixel value assigned to 1's and another assigned to 0's. XRecolorCursor() changes these pixel values. If the cursor is being displayed on a screen, the change is visible immediately. On some servers, these color selections are read/write cells from the colormap, and can't be shared by applications.
Structures:
typedef struct {
unsigned long pixel;
unsigned short red, green, blue;
char flags;
/* DoRed, DoGreen, DoBlue */ char pad; } XColor;
Errors:
BadCursor
