; blend SRC_ALPHA ONE_MINUS_SRC_ALPHA

; If clear is 1, the followed steps are:
; 1. Copy the screen contents
; 2. Clear the screen
; 3. Distort the copies pixels
; 4. Put the contents again over the screen
; If fClear is set to 0, the step 2 is omitted
fClear 1

; The alpha variation from start to end times
