In get_tex_memcpy, when copying texture data directly from source to destination (when row strides match for both src and dst), the copy size is currently calculated using the full texture height instead of the sub-region height parameter that was passed. This can cause a read past the end of the mapped buffer when y-offset is greater than zero, leading to a segfault. Fixes CTS test (from crash to pass): * GL45-CTS/get_texture_sub_image/functional_test v2: (Jason) Use the passed 'height' instead of copying til the end of the buffer (tex-height - yoffset).
