Description
Currently rive lacks the ability to update pixels in already created textures. I'm finding issues trying to efficiently update an audio Spectrogram i'm updating on the CPU and transfer it efficiently on the GPU at 60fps.
Consider adding:
virtual void Texture::updatePixels (uint32_t x, uint32_t y, uint32_t width, uint32_t height, const uint8_t rgbaData[], uint32_t strideBytes) = 0;

Research direction
Start at the Texture API entry point and trace how textures are currently created and transferred to the GPU. Define the updatePixels interface with the requested region, RGBA data, and stride parameters, then verify that callers can update only a subregion without recreating the full texture.
