Matthew Waters	55bcdcf01a	gl: actually use the highp specifier ... 675415bf2e contained a typo that incorrectly used the mediump specifier instead of highp.	2019-02-28 23:39:21 +11:00
Matthew Waters	675415bf2e	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.	2019-02-28 17:26:32 +11:00
Matthew Waters	2d62b2910c	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.	2017-12-09 19:32:19 +00:00
Matthew Waters	ef319c7b8f	glshaderstrings: fixup the external-oes fragment shader ... The wrong sampler type was used s/sampler2DExternalOES/samplerExternalOES/	2017-12-09 19:32:10 +00:00
Matthew Waters	b1ac029b87	glslstage: expose the default shader strings as public ... Add some other simple strings for external-oes textures or transforming the texture coordinates with a transformation matrix	2017-12-09 19:32:10 +00:00
