-""" Units conversions and constants
-
-The purpose of the module is to keep Sugar independent from the
-screen size, factory and DPI. There a few use cases that needs
-to be considered:
-
- - The XO display. The screen DPI is 201 and the screen
- resolution is 1200x900. The screen factor is 4:3.
- - The Sugar emulator runned on traditional screens. Resolution
- is variable, ranging from 800x600 up to 1200x900. The DPI
- is usually but not necessarily 96. The screen factor is
- either 4:3 or 16:9
- - Other embedded devices. DPI, screen resolution and screen
- factor are variable.
-
-To achieve the goal a few rules needs to be respected when
-writing code for Sugar:
-
- - Never use absolute positioning. Use the layout facilities
- provided by HippoCanvas. If you need custom layouts make
- sure they adapt to different screen resolutions.
- - Never specify sizes, fonts, borders or padding using pixels.
- Instead use the device independt units provided by this
- module.
-
-We are currently providing the following resolution independent
-units:
-
- - Points.
- - Grid. One cell of the screen grid as specificed by the HIG.
- - Microgrid. One microcell of the screen grid as
- specificed by the HIG.
- - A set of icon sizes as specified by the HIG (standard, small,
- medium, large, xlarge).
-
-Just scaling UI elements on the base of the screen DPI is not
-enough to provide a good experience. For example on smaller
-screens smaller fonts or icons might be acceptable to gain
-screen aestate. For this reason a constant zoom factor is
-applied to all the transformation from resolution independent
-units to device units.
