1543616 - Call TextureHost::PrepareForUse() when mCompositableCount becomes from 0 to 1

Status: RESOLVED FIXED

(Core :: Graphics: WebRender, enhancement)

Description

[Sotaro Ikeda [:sotaro]]

By Bug 1529870, the PrepareForUse() is called in WebRenderImageHost::SetCurrentTextureHost(). It works with single buffer mode android SurfaceTexture for WebGL. But it does not work well with video's SurfaceTexture, since multiple TextureHosts are received and a TextureHost might be skipped.

Then we want to know the timing of mCompositableCount becomes from 0 to 1. In this timing, we want to call the PrepareForUse().
