Subject: gbm: Remove 64x64 restriction from GBM_BO_USE_CURSOR
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=be5e5b6c9364fcac8f26bc2875ffcfbaa4e17b45;p=mesa.git

gbm: Remove 64x64 restriction from GBM_BO_USE_CURSOR

GBM_BO_USE_CURSOR_64X64 is kept so that existing users of GBM continue to
build, but it no longer rejects widths or heights other than 64.
