Oncoprint heatmap legend renders as plain red block

[fedde-s]

In the rc development branch, the legend for heatmaps in the Oncoprint no longer renders as a gradient from blue to black to red, but as a plain red block all the way from -3 to 3.

@adamabeshouse, do you know what might have caused this?

[adamabeshouse]

I haven't made any related changes.. perhaps related to @rnugraha's recent changes?

Yes. A git bisect shows that the bug was introduced by commit e19e28f.

I believe that this is being addressed by pull request #3168.
