gsk: Rework how GLSL shaders are built The GL renderer should build the GLSL shaders using GskShaderBuilder. This allows us to separate the common parts into separate files, and assemble them as necessary, instead of shipping one big shader per type of GL API (GL3, GL legacy, and GLES). 2016-07-03 20:12:22 +00:00			`void main() {`
gl renderer: Rework program creation Make sure all uniform names have to match between the shader names and the _location integers we save in every Program struct. 2017-11-30 17:47:55 +00:00			`gl_Position = u_modelview * u_projection * vec4(aPosition, 0.0, 1.0);`

Use the projection to flip around the content Since we use an FBO to render the contents of the render node tree, the coordinate space is going to be flipped in GL. We can undo the flip by using an appropriate projection matrix, instead of changing the sampling coordinates in the shaders and updating all our coordinates at render time. 2016-08-02 15:58:47 +00:00			`vUv = vec2(aUv.x, aUv.y);`
