++* ioctl(fd, FBIO_EP93XX_CURSOR, ep93xx_cursor *)
++*
++* "data" points to an array of pixels that define the cursor; each row should
++* be a multiple of 32-bit values (i.e. 16 pixels). Each pixel is two bits,
++* where the values are:
++*
++* 00 => transparent 01 => invert 10 => color1 11 => color2
++*
++* The data is arranged as follows (per word):
++*
++* bits: |31-30|29-28|27-26|25-24|23-22|21-20|19-18|17-16|
++* pixel: | 12 | 13 | 14 | 15 | 8 | 9 | 10 | 11 |
++* bits: |15-14|13-12|11-10| 9-8 | 7-6 | 5-4 | 3-2 | 1-0 |
++* pixel: | 4 | 5 | 6 | 7 | 0 | 1 | 2 | 3 |
++*
++* Regardless of the frame buffer color depth, "color1", "color2",
++* "blinkcolor1", and "blinkcolor2" are 24-bit colors since the cursor is
++* injected into the data stream right before the video DAC.
++*
++* When "blinkrate" is not zero, pixel value 10 will alternate between "color1"
++* and "blinkcolor1" (similar for pixel value 11 and "color2"/"blinkcolor2").
++*
++* "blinkrate" ranges between 0 and 255. When 0, blinking is disabled. 255 is
++* the fastest blink rate and 1 is the slowest.
++*
++* Both "width" and "height" must be between 1 and 64; it is preferable to have
++* "width" a multiple of 16.

++*
++* The line starts at ("x1","y1") and ends at ("x2","y2"). This means that
++* when using a pattern, the two coordinates are not transitive (i.e. swapping
++* ("x1","y1") with ("x2","y2") will not necessarily draw the exact same line,
++* pattern-wise).
++*
++* "pattern" is a 2 to 16 bit pattern (since a 1 bit pattern isn't much of a
++* pattern). The lower 16 bits define the pattern (1 being foreground, 0 being
++* background or transparent), and bits 19-16 define the length of the pattern
++* (as pattern length - 1). So, for example, "0xf00ff" defines a 16 bit
++* with the first 8 pixels in the foreground color and the next 8 pixels in the
++* background color or transparent.
++*
++* LINE_PRECISE is used to apply angularly corrected patterns to line. It
++* should only be used when LINE_PATTERN is also set. The pattern will be
++* applied along the length of the line, instead of along the length of the
++* major axis. This may result in the loss of fine details in the pattern, and
++* will take more time to draw the line in most cases.
