Implements a temporary compatibility fix for map icon sizing in older Omni store builds. These builds render uploaded marker icons at their native image size, causing 128 px icons to appear larger than the 32 px built-in map pins.
Changes
Added support for requesting uploaded type icons at the map’s 32 px size using the px=32 query parameter.
Works with both plain and badged icons.
Other px values are ignored.
ETags now distinguish between original, badged, and resized icon variants.
Added server-side 32×32 PNG rendering for uploaded icons.
Images are resized with transparent padding where necessary.
Resized results are cached by icon checksum, badge style, and size.
Invalid or missing image data returns no resized rendition.
Added legacy Omni client detection based on:
X-Resgrid-Client
X-Resgrid-App-Version
The fullSizeIcons request flag
Updated map marker responses so recognized legacy Omni store builds receive icon URLs with px=32.
Preserved existing 128 px icon URLs for:
Fixed Omni builds sending fullSizeIcons=true
Older legacy app versions
Web, Electron, unknown, or missing client/version information
Requests without the new flag
Added tests covering:
32 px image rendering and caching
Invalid and null image handling
Client/version matching behavior
URL updates for plain and badged icons
Mapping controller behavior for legacy and fixed Omni builds
The change adds cached map-size icon rendering and an optional pixel-size parameter for icon requests. It also adds client and app-version checks that adjust map marker icon URLs for eligible clients unless they request full-size icons.
RenderAtMapSize pads icons to TypeIcons.MapSize, encodes them as PNG, and caches results for keyed requests. TypeIconsController.Get accepts px; when it matches the map size and rendering succeeds, the response uses the rendered image and a size-specific ETag variant.
LegacyOmniPinIcons checks the client, app-version major, and fullSizeIcons flag. When the rule applies, MappingController updates marker icon URLs to use the map-size rendition.

Merge Risk: Low · up to 9eace
Map-size icon rendering adds a process-local cache that bypasses the repository's standard cache abstraction. No user-facing failure was established, so this is a bounded follow-up to settle before or soon after merge.

Explanation
The title "RG-T152 Map Icon Size Issue for Apps" names the main change. The changeset adds map-size rendering of type icons (MapIconPinRenderer.RenderAtMapSize, TypeIconsController px parameter) and a LegacyOmniPinIcons helper that routes app builds to 32 px map icons. The title references a ticket ID and a general topic, so it is broad, but it is related to the change and does not describe anything absent from the changeset.

Blocking async execution in GetMapDataAndMarkers violates the “Await async operations properly” rule and can cause deadlocks. Replace .Result with end-to-end async/await and configure awaits appropriately.

Route the new cache through ICacheProvider.
SizedCache introduces another process-local cache outside the repository cache abstraction. Use ICacheProvider for the map-size results instead of adding a separate cache implementation.
Based on learnings, “All caching goes through ICacheProvider — implemented by AzureRedisCacheProvider.”
