<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Now that all layers are aware of the actual integer brightness value and the maximum brightness value, rework «brightness up/down» actions.<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
See background explanation in previous RR.</p>
<hr style="text-rendering: inherit;margin: 0;padding: 0;white-space: normal;border: 1px solid #ddd;line-height: inherit;" />
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Implement brightnessStep logic.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Introduce brightnessStep, brightnessStepMax, brightnessStepChanged, setBrightnessStep D-Bus endpoints in org.kde.Solid.PowerManagement.Actions.BrightnessControl.<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
Introduce correspoding D-Bus endpoints in org.kde.Solid.PowerManagement.Actions.KeyboardBrightnessControl.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Use step-based logic for increase/decrease brightness actions.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">This makes the increase/decrease brightness actions behave as if the brightness steps are pre-calculated.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Also, brightness percentage is now rounded everywhere (it was just cast to int without rounding before), now that the inner logic does not depend on the percentage anymore.<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
Before this patch I was not sure if this would make things look worse or not.</p>
<hr style="text-rendering: inherit;margin: 0;padding: 0;white-space: normal;border: 1px solid #ddd;line-height: inherit;" />
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">An illustraton:<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
Before: http://oserv.org/tests/kde/powerdevil/brightness_before.php<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
After: http://oserv.org/tests/kde/powerdevil/brightness_after.php, this script shares the same code for calculating steps count.</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Works on acpi_video0 with 10 steps, asus::kbd_backlight with 3 steps, and intel_backlight notebook with 4000+ steps.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">The BackendInterface::calculateStepsCount() logic was separately tested for all possible max_brightness values.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Only upower backend was tested.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">HAL backend uses variable m_cachedKeyboardBrightness before it is initialized, and I am not the one who wrote it that way.</p></pre>
