+/*
+The first four bytes of cursor data give information about the cursor: 
+
+Byte 1: Size in pixels-per-side. Cursors are always square; currently, only 16-by-16 
+cursors are allowed. 
+Byte 2: Color depth in bits-per-pixel. Currently, only one-bit monochrome is allowed. 
+Bytes 3&4: Hot spot coordinates. Given in "cursor coordinates" where (0,0) is the upper 
+left corner of the cursor grid, byte 3 is the hot spot's y coordinate, and byte 4 is its x 
+coordinate. The hot spot is a single pixel that's "activated" when the user clicks the mouse. 
+To push a button, for example, the hot spot must be within the button's bounds. 
+
+Next comes an array of pixel color data. Pixels are specified from left to right in rows starting at 
+the top of the image and working downward. The size of an array element is the depth of the 
+image. In one-bit depth... 
+
+the 16x16 array fits in 32 bytes. 
+1 is black and 0 is white. 
+
+Then comes the pixel transparency bitmask, given left-to-right and top-to-bottom. 1 is opaque, 0 is 
+transparent. Transparency only applies to white pixels—black pixels are always opaque.
