-+*
-+* "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.
