Detailed Description

Base class for texture-generating nodes.

Provides common functionality for managing texture dimensions and pixel data in RGBA float format. Derived classes implement compute_frame() to define specific texture generation or processing algorithms.

Texture data is stored as a flat array in row-major order: [R0,G0,B0,A0, R1,G1,B1,A1, ..., Rn,Gn,Bn,An]
