Extra memcpy in GLES renderer patch

SDL 1.3 rev. hg-4510:6f8175ad0335

In function GLES_RenderCopy() in SDL_renderer_gles.c:819 there is one memcpy() that can be avoided if we're updating whole texture. 
Because of that the SDL 1.3 in compatibility mode is working even slower than software rendering in SDL 1.2.

Patch attached.

Thank you very much for your patch for SDL 1.3!

Do you give me permission to release your code with SDL 1.3 and future
versions of SDL under both the LGPL and a closed-source commercial
license?

Of course you have the permission.
Comment 3 Sam Lantinga 2010-07-14 07:31:55 UTC
