This fixes a few problems that occur when only using a GLES2 header. • The use of GL_CLAMP_TO_BORDER and GL_MIRRORED_REPEAT were moved from cogl-pipelinelayer-state.h to cogl-sampler-cache-private.h but the corresponding defines were not. • cogl-sampler-cache.c was using GL_TEXTURE_WRAP_R but this is only defined as GL_TEXTURE_WRAP_R_OES from the GLES2 header so it needs a #define. • cogl-framebuffer-private.h uses GLuint but it does not include cogl-gl-header.h. It gets away with this when GLX support is enabled because the GL header would be included via glx.h.
