glshader: fix default external-oes shaders
...
In glsl, #extension directives need to before other non-preprocesser
directives. We were placing the precision qualifier before that. Fix
by moving the #extension to the first line in the shader.

gl: try to use highp precision where supported
...
The use of mediump as a specifier in GLSL shaders will have limited
resolution and when used as texture coordinates may become inaccurate
over texture sizes of 1024.

gl: take the affine transformation in NDC
...
Provide a function to get the affine matrix in the meta in terms of NDC
coordinates and use as a standard opengl matrix.
Also advertise support for the affine transformation meta in the allocation
query.
