Remarks
PURPOSE: Provides the FMX-specific bitmap backend used by TatukGIS DK for rendering, pixel access, bitmap import/export, and viewer creation on FireMonkey target platforms.
BEHAVIOR: Wraps an FMXTBitmap instance and exposes it through the DK bitmap abstraction. This platform supports optional premultiplied bitmap storage, which can affect how pixel values are stored and blended.
CONSTRAINTS: Available only in FMX applications and depends on FireMonkey bitmap classes and pixel formats.
