Subject: [PATCH 07/50] egl_dri2: set pbuffer config attribs to 0 for
|
|
non-pbuffer configs
|
|
|
|
If the EGL_PBUFFER_BIT isn't set in the surface type, don't set the
|
|
EGL_MAX_PBUFFER_WIDTH, EGL_MAX_PBUFFER_HEIGHT and
|
|
EGL_MAX_PBUFFER_PIXELS attributes to non-zero values when adding an
|
|
EGL config. If the EGL_PBUFFER_BIT is set, don't override non-zero
|
|
values from the DRI config.
