One case we need force clip when download/upload a drm_texture pixmap. Actually, this is only meaningful for testing purpose. As we may set the max_fbo_size to a very small value, but the drm texture may exceed this value but the drm texture pixmap is not largepixmap. This is not a problem with OpenGL. But for GLES2, we may need to call glamor_es2_pixmap_read_prepare to create a temporary fbo to do the color conversion. Then we have to force clip the drm pixmap here to avoid large pixmap handling at glamor_es2_pixmap_read_prepare. Signed-off-by: Zhigang Gong <zhigang.gong@linux.intel.com>
X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
