+\fB-alphacut\fR \fIn\fR
+.IP
+When using the XFIXES extension for the cursor shape,
+cursors with transparency will not be displayed exactly
+(but opaque ones will). This option sets n as a cutoff
+for cursors that have transparency ("alpha channel"
+with values ranging from 0 to 255) Any cursor pixel with
+alpha value less than n becomes completely transparent.
+Otherwise the pixel is completely opaque. Default 255
+.IP
+Note: the options \fB-alphacut,\fR \fB-alphafrac,\fR and \fB-alphafrac\fR
+may be removed if a more accurate internal method for
+handling cursor transparency is implemented.
+.PP
+\fB-alphafrac\fR \fIfraction\fR
+.IP
+With the threshold in \fB-alphacut\fR some cursors will become
+almost completely transparent because their alpha values
+are not high enough. For those cursors adjust the
+alpha threshold until fraction of the non-zero alpha
+channel pixels become opaque. Default 0.33
+.PP
+\fB-alpharemove\fR
+.IP
+By default, XFIXES cursors pixels with transparency have
+the alpha factor multiplied into the RGB color values
+(i.e. that corresponding to blending the cursor with a
+black background). Specify this option to remove the
+alpha factor. (useful for light colored semi-transparent
+cursors).
