Subject: [M108 Migration][API] Add ewk_context_max_refresh_rate_set
X-Git-Tag: submit/tizen/20230227.160252~84
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=refs%2Fchanges%2F07%2F288007%2F4;p=platform%2Fframework%2Fweb%2Fchromium-efl.git

[M108 Migration][API] Add ewk_context_max_refresh_rate_set

To reduce current consumption, some devices need to set screen FPS limitation.
This api is added to set screen FPS limitation.

If max refresh rate is set as 30, each thread will work as below.
1) With |setInterval(16ms)|.
 - Renderer main thread : 60fps
 - Renderer raster thread : 30fps
 - Renderer compositor thread : 30fps
 - UI main thread : 30fps

2) With |setInterval(20ms)|
 - Renderer main thread : 50fps
 - Renderer raster thread : 30fps
 - Renderer compositor thread : 30fps
 - UI main thread : 30fps

3) With |requestAnimationFrame|
 - Renderer main thread : 30fps
 - Renderer raster thread : 30fps
 - Renderer compositor thread : 30fps
 - UI main thread : 30fps
