DO NOT MODIFY THIS FILE UNLESS YOU KNOW WHAT YOU ARE DOING!
|
|
|
|
This file is specifically designed to create a page larger than
|
|
any screen fennec could run on (to allow panning in both axes).
|
|
It is filled with 100x100 pixel boxes that are of unique colour,
|
|
so that we can identify exactly what part of the page we are
|
|
rendering at any given time. The colours are specifically chosen
|
|
so that adjacent boxes have a fairly large variation in colour,
|
|
and so that errors due to 565/888 conversion are minimised. This
|
|
is done by dropping the bottom few bits on each color channel,
|
|
so that conversion from 888->565 is pretty much lossless, and any
|
|
variation only comes in from however the drivers do 565->888.
|
|
|
|
A lot of the tests depend on this behaviour, so ensure that all
|
|
the tests pass (on a variety of screen sizes) when making any
|
|
changes to this file.
