Detailed Description

Base class for BSB (Maptech/NOS) format nautical charts.

Provides core functionality for handling BSB format raster nautical charts. Implements chart rendering, coordinate transformations, and utility functions.

Key features include:

Chart initialization and loading
Rendering of chart views on different devices (DC, OpenGL)
Coordinate conversions between lat/lon and chart pixels
Color scheme management
Chart scaling and zooming
Caching mechanisms for improved performance

Find closest valid scale that's a power of 2 multiple of chart's native scale.

Parameters

target_scale	Target scale in physical pixels per meter.
scale_factor_min	Minimum allowed scale multiplier (e.g., 0.01 allows zoom in to 100x).
scale_factor_max	Maximum allowed scale multiplier (e.g., 64 allows zoom out to 1/64x).
