Description Bruce Merry 2013-12-30 12:00:21 UTC

When I create a 1D texture with width 6 and border 1, querying GL_TEXTURE_WIDTH and GL_TEXTURE_BORDER return 4 and 0 respectively, instead of 6 and 1. I will attach a piglit test.

Mesa 10.0.1 configured with --enable-xlib-glx --disable-dri --with-gallium-drivers=swrast --with-egl-platforms=x11 and LD_LIBRARY_PATH=<mesadir>/lib (i.e. not the gallium subdirectory).

We won't be fixing this.  We removed support for texture borders since few (none?) of our hardware drivers support them.

When glTexImage() is called with border=1 we tweak the pixel unpack params and only store the image w/out the border.
