Subject: On emulator, pBuffer display is y-inverted.
X-Git-Tag: Tizen_Studio_1.3_Release_p2.3.1~1006^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2261ec7a54f9cf91eb593a82b3a10787c6328e0e;p=sdk%2Femulator%2Fqemu.git

On emulator, pBuffer display is y-inverted.
With this patch, the buffer data is y-inverted before texture generation.
This induces a performance penalty, however display is no longer inverted.

Limit this patch to 32 bpp.
