Then EGL_WIDTH and EGL_HEIGHT are checked to verify 38 that they report the new native window size. 39 40 The back_buffer.* tests create an EGL_BUFFER_PRESERVED surface and draw 41 a test image on it. The native window is resized, and the back buffer is 42 checked to see that it is similar to the original test image in some 43 corner. 44 45 The pixel_density.* tests query the EGL_HORIZONTAL_RESOLUTION and 46 EGL_VERTICAL_RESOLUTION attributes of the surface both before and after 47 resizing. These are compared to the size of the native image in physical 48 display pixels. An error is reported if the results are inconsistent, 49 i.e. if they imply that the size of a physical display pixel changed 50 size during resizing. 51
