Options Dialog Box Configuration Notes:

Particle Count = Stipulates the number of particles that are allocated for the particle generator to use.  This amount can be either decreased for increased performance or augmented for a much "richer" effect to a point.

Particle Speed = A modifer that governs how fast a particle moves depending on the direction specified in the particular demo.  Note that the effect may become something entirely new if this value is varied too much.

Top X Pos = The upper left hand corner of the particle "limit" rectangle created by the user along the x-axis.

Top Y Pos = The upper left hand corner of the particle "limit" rectangle created by the user along the y-axis.

Bottom X Pos = The lower right hand corner of the particle "limit" rectangle created by the user along the x-axis.

Bottom Y Pos = The lower right hand corner of the particle "limit" rectangle created by the user along the y-axis.

Fade Speed = The speed at which a particle in the particle generator fades.

Point Speed = The speed at which a particle travels from its place of origin to the top middle portion of the rendering rectangle.  Note that if a higher number is stipulated, the flame will be more narrow.

Particle Colors = The color that the particle expresses.  A value of higher than 100 on each component for RGB will automatically randomize each particle's color, thus creating a "rainbow". 


Rendering Rectangle:
(x,y)==================== <-Top x and y
|			|
|			|
|			|
|			|
|			|
====================(x,y) <-Bottom x and y

Particles are only allowed to exist in this region; traversing out of this region will result in re-allocation to the place of origin based on the particle generator's behavior.
