Buffer not properly resized in the D3D11 backend #897

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?

Create a buffer, load some data into it.
Increase the size of the buffer.
Upload more data to it using map/unmap.
Read back the data using map/unmap and check that it matches the original.
The data will not match.

Buffer11::getLatestBufferStorage() fails to resize the buffer hence ANGLE uses 
a D3D buffer which is too small for the content.
