Remove PerformClipping(),CanClipSelf() and the related logic in LTHCommon.
There is a precision lost issue for texture layers with CSS
transforms(Scaling) when applying TextureDrawQuad::PerformClipping()
to avoid explicitly setting a scissor. The rect is first divided by
the scale_factor, then round to integer value and finally multiplied
by the scale_factor in GLRenderer::EnqueueTextureQuad(). The round
process loses precision and the later scale operation enlarges the
error. This error leads to wrong width and height drawn and
introduces visual defects.
