Simon Ser 677a3f2f88 render/gles2: default to highp if available
The spec [1] says that the maximum value for a mediump float
is at least 2¹⁴ in section 4.5.2. However, when using a 4k
resolution texture coordinates will exceed this value. This causes
issues on drivers which implement mediump as a 16-bit [2].

Switch to highp. There's a twist: on GLES2, support for highp is
optional. So we need to guard it with cute GL_FRAGMENT_PRECISION_HIGH
ifdefs.
