* that corresponds to logical coordinate (x,y).
*
* For example, suppose the mapping mode is MM_TEXT. Given the following definition of that

*
* This MUST be one of the following:
*
* MM_TEXT (= 0x0001):
* Each logical unit is mapped to one device pixel.
* Positive x is to the right; positive y is down.
*
* MM_LOMETRIC (= 0x0002):

* Positive x is to the right; positive y is up.
*
* MM_HIENGLISH (= 0x0005):
* Each logical unit is mapped to 0.001 inch.
* Positive x is to the right; positive y is up.
*
* MM_TWIPS (= 0x0006):
* Each logical unit is mapped to one twentieth (1/20) of a point.
* In printing, a point is 1/72 of an inch; therefore, 1/20 of a point is 1/1440 of an inch.
* This unit is also known as a "twip".
* Positive x is to the right; positive y is up.

* that is, one unit along the x-axis is equal to one unit along the y-axis.
* The META_SETWINDOWEXT and META_SETVIEWPORTEXT records specify the units and the
* orientation of the axes.
* The processing application SHOULD make adjustments as necessary to ensure the x and y

* are at the same point on the drawing surface, what is the physical coordinate (x',y')
* that corresponds to logical coordinate (x,y).
*
* For example, suppose the mapping mode is MM_TEXT. Given the following definition of that
* mapping mode, and an origin (0,0) at the top left corner of the drawing surface, logical
* coordinate (4,5) would map to physical coordinate (4,5) in pixels.

* Now suppose the mapping mode is MM_LOENGLISH, with the same origin as the previous
* example. Given the following definition of that mapping mode, logical coordinate (4,-5)
* would map to physical coordinate (0.04,0.05) in inches.
*
* This MUST be one of the following:
*
* MM_TEXT (= 0x0001):
* Each logical unit is mapped to one device pixel.
* Positive x is to the right; positive y is down.
*
* MM_LOMETRIC (= 0x0002):
* Each logical unit is mapped to 0.1 millimeter.
* Positive x is to the right; positive y is up.
*
* MM_HIMETRIC (= 0x0003):
* Each logical unit is mapped to 0.01 millimeter.
* Positive x is to the right; positive y is up.
*
* MM_LOENGLISH (= 0x0004):
* Each logical unit is mapped to 0.01 inch.
* Positive x is to the right; positive y is up.
*
* MM_HIENGLISH (= 0x0005):
* Each logical unit is mapped to 0.001 inch.
* Positive x is to the right; positive y is up.
*
* MM_TWIPS (= 0x0006):
* Each logical unit is mapped to one twentieth (1/20) of a point.
* In printing, a point is 1/72 of an inch; therefore, 1/20 of a point is 1/1440 of an inch.
* This unit is also known as a "twip".
* Positive x is to the right; positive y is up.
*
* MM_ISOTROPIC (= 0x0007):
* Logical units are mapped to arbitrary device units with equally scaled axes;
* that is, one unit along the x-axis is equal to one unit along the y-axis.
* The META_SETWINDOWEXT and META_SETVIEWPORTEXT records specify the units and the
* orientation of the axes.
* The processing application SHOULD make adjustments as necessary to ensure the x and y
* units remain the same size. For example, when the window extent is set, the viewport
* SHOULD be adjusted to keep the units isotropic.
*
* MM_ANISOTROPIC (= 0x0008):
* Logical units are mapped to arbitrary units with arbitrarily scaled axes.
