Format a feature map for display.

Take an Image<float> feature map as input and convert it to PixRGB<byte> by either multiplying the values by a factor or by normalizing them to 0 .. 255 (if factor is 0.0), and then using a given color map (which will also be displayed if showColorScale is true). Then rescale to the specified dims, using interpolation if desired. Then write a descriptor label in the top-left corner using a large font, and finally show the original range of values in the bottom-right corner uing a tiny font.

col the foreground color for the written text
bg the background color for the written text
max_chars_per_line if non-zero, then each line of text will be truncated at this many characters
fontwidth the max font width unless it is zero, in which case it will be determined automatically to fit the text in the box.

Warp image in 3D onto z-map.

Parameters:
ima Input image
zmap Height map of same size as ima
pitch 3D pitch angle, in degrees
yaw 3D yaw angle, in degrees
dims The result will have these dimensions, unless the dimensions are empty (i.e. 0-by-0), in which case the result will be the best size computed from ima's size and the pitch and yaw angles.
