CxImage is used for image conversion for clipboard support. CxImage have currently some issue: - library is old and unsupported; - required an old libpng library. Currently the MingW binary we distribute due to some issue have PNG disabled (so no clipboard image support). Note that currently we support (before and after this patch) only BMP and PNG. PNG is required as the default agent format. However Windows programs wants to have BMP (specifically DIB) in the clipboard. This patch remove CxImage and use directly libpng (BMP is supported directly by Windows APIs). Tested with various formats and the compiled agent with a Linux client. The main concern is actually the possible problem to support some weird/old BMP file formats.
