RGBF
c = RGBF (r, g, b)
Returns the RGB color code for the specified color values.
r, g and b are the three color
channels red, green and blue and take floating point values from 0 to 1
for each of the colors. Values outside that range will be clamped. The
return value is a negative 24bit value to be used by the drawing
functions.

Example 1
c = rgbf(0.047, 0.48, 0.94)
rect 10, 10, 50, 50 color c filled
rect 60, 10, 100, 50 color rgbf(0.047, 0.48, 0.94) filled
Example 2: Clamping of values
c1 = rgbf(-0.55, 2.5, 0.94) ' same as rgbf(0, 1, 0.94)
c2 = rgbf(0, 1, 0.94)
rect 10, 10, 50, 50 color c1 filled
rect 60, 10, 100, 50 color c2 filled

For c = 0 to 1 step 0.01
