Bounds in heatmap

[plaumiere]

In heatmap I have observed that another bounds other than [0,1] is not allowing.
After checking the code this issue could be resolved by replacing the max bound set to 1 (for determining the y coordinate of p) by the max y bound as parameter in function RenderHeatmap().

Good job

Thanks! It has been resolved, and the demo has been updated to show heatmap bounds in action: 0a3442f

p.y = bounds_max.y - (0.5*h + r*h);
