true on GLES3+ / GL3+ / WebGL2 — runtimes where texImage2D accepts sized internalformat values (e.g. GL_RGBA8, GL_DEPTH_COMPONENT16). WebGL1 / GLES2 require unsized formats where internalformat == format. Sized formats are needed for MSAA-resolve compatibility (the resolve target's internal format must match the multisample renderbuffer's GL_RGBA8).
