error codes, state queries, framebuffer targets, texture binding targets, and
active texture units to `pp_renderer_gl`.
`NodeStrokePreview` brush preview rendering now delegates depth/scissor/blend
state, viewport/clear-color queries, active texture units, 2D texture targets,
copy targets, sampler filters/wraps, and destination-feedback copy/fetch
decisions to `pp_renderer_gl` and `pp_paint_renderer`.

2D texture unbinds, 2D texture targets, copy targets, sampler filters/wraps,
and destination-feedback copy/fetch decisions to `pp_renderer_gl` and
`pp_paint_renderer`. Retained `Canvas` stroke/thumbnail paths and `NodeCanvas`
panorama rendering use the same tested active-texture dispatch for their
texture-unit switches.
Legacy `Texture2D`, `TextureManager`, `Sampler`, and `RTT` public headers no
longer expose raw OpenGL enum defaults; default texture formats, sampler
filters/wraps, and render-target formats are resolved through backend-owned
