This specifies a bit-strip to use as the sequence of images for all the tool buttons. The standard Win95 tools are all 16x16 pictures, but you may find 19x19 more comfortable. You should supply a single integer array, for example to provide the pictures for 12 tools you will need a 16 x 192 array of colour values. You can make this in Windows Paint in the usual way (be sure to save as 16 colour), then read the bits property into the workspace, or you can use the supplied Picstrip namespace as your editor.
