Cylindrical equidistant projection
==================================

This simple cylindrical projection is really a linear scaling of longitudes and
latitudes. The most common form is the Plate Carrée projection, where the
scaling of longitudes and latitudes is the same. All meridians and parallels
are straight lines.

**q**\ [*lon0*/\ [*lat0*/]]\ *scale* or **Q**\ [*lon0*/\ [*lat0*/]]\ *width*

- **q** or **Q**: Sets the projection type.
- *lon0*: Sets the central meridian [Optional, default is the middle of the map].
- *lat0*: Sets the standard parallel [Optional, default is the equator]. When
  supplied, *lon0* must be supplied as well.
- *scale* or *width*: Sets the map size.
