Steps to reproduce:

The default tile size of WebRender is 1024*512, this value is pretty good for average desktop's screen. However, for those devices with small screen, big tile size will waste significant amount of memory. Hence I'd like to upload a patch to provide a configurable tile size for WebRender.

Comparing the GPU memory consumption of different tile size(1024x512 v.s. 256x256) on a KaiOS test phone with 480x1440 screen:

+------------------+----------------+---------------+
|                  | Tile: 1024x512 | Tile: 256x256 |
+------------------+----------------+---------------+
|boot ready        | 54,548,070     | 40,539,648    |
