Description: Video buffer format and color depth
This option allows you to configure whether video data is stored in RGBA or
BGRA byte order in the internal video buffers. This setting (together with
texture_format) may affect texture upload performance. The option should not
be shared between computers, since appropriate values may differ for other
operating system or OpenGL GPU vendors. Valid values are:
Value: bgra ("32-bit BGRA")
This is the default setting as it has been verified to provide
best 32-bit color performance with most OpenGL drivers.
Value: rgba ("32-bit RGBA")
Depending on your system, this may give better 32-bit performance.
Value: rgb565 ("16-bit")
Using this format means that less data needs to be uploaded to the
GPU. May be quite a bit faster on slower systems.
