Graphics: fixed error when putimage and drawrect do not draw pixels
on right and bottom window sides
Processes: fixed kernel fault when program to load is too big
Programs: EYES: now it works with new kernel (rev. 130). Size optimization.
Blinking deleted.

; Position of "eyes" is fixed. To close "eyes" just click on them.

|
|
; NOTE: quite big timeout is used to disable blinking when redrawing.
|
|
; If "eyes" blink on your system, enlarge the TIMEOUT. If not, you can
|
|
; decrease it due to more realistic movement.
