Subject: draw: Handle failure to allocate aligned_constant_storage.
X-Git-Tag: 062012170305~3165
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9e29cdbe95810de8658dfd1cabf1a7d87264c2f7;p=profile%2Fivi%2Fmesa.git

draw: Handle failure to allocate aligned_constant_storage.

Also, actually update const_storage_size, therefore avoiding to
unnecessarily reallocate aligned_constant_storage every single time
draw_vs_set_constants() is called.
