Breaking: #43085 - Change GFX settings prefix im_* to generic processor_*

See Issue #43085

Description

Graphics processor settings for Image- or GraphicsMagick have been renamed in LocalConfiguration.php. The former prefix im\_ has been replaced with the unified prefix processor\_.

Negative namings like noScaleUp have been changed positive counterparts. During the conversion the previous configuration values are negated to reflect the changes in semantics of these options.

In addition references to specific versions of ImageMagick/GraphicsMagick have been removed from settings names and values. For a detailed list of changes please consult the information in the migration section.

The unused configuration option image\_processing has been removed without replacement.

The processor specific configuration option colorspace has been namespaced below the processor\_ hierarchy.

Impact

Existing settings in LocalConfiguration.php are automatically migrated through a silent upgrader when entering the Install Tool. If you modify the settings in AdditionalConfiguration.php or rely on them inside an extension you need to update those.

Affected Installations

Installations which modify those settings directly or access them.
