This patch series aims to add PNG support using libpng to screendump method. Currently screendump only supports PPM format, which is uncompressed and not standardised.
PATCH 1 phases out CONFIG_VNC_PNG parameter and replaces it with CONFIG_PNG which detects libpng support. PATCH 2 contains core logic for PNG creation from pixman using libpng. HMP command equivalent is also implemented in this patch. v3->v4 - Added condition to check for libpng only in PNG option is allowed v2->v3 - HMP implementation fixes for png. - Used enum for image format. - Fixed description and updated QEMU support version. v1->v2: - Removed repeated alpha conversion operation. - Modified logic to mirror png conversion in vnc-enc-tight.c file. - Added a new CONFIG_PNG parameter for libpng support. - Changed input format to enum instead of string. - Improved error handling.
