v1.0.0: Inaugural Release of liblamina

• Inaugural Release of liblamina (formerly libqgl):

  • Consolidated cross-platform 2D graphics layer and flexbox UI layout engine in pure C.
  • Unified immediate-mode rendering across desktop displays (OpenGL via GLFW on Linux X11/Wayland, macOS, Windows) and direct hardware on embedded Linux (via memory-mapped /dev/fb0 without X11 or Wayland).
  • Standalone shared library lib/liblamina.so with pkg-config package lamina.pc.

• API Modernization (lam_* / LAM_*):

  • Reorganized public headers under include/ttypt/:
    • <ttypt/lam.h> — Core rendering, textures, colors, and lifecycle.
    • <ttypt/lam-ui.h> — Declarative flexbox UI tree, styling, and layout engine.
    • <ttypt/lam-font.h> — Pre-rendered bitmap font loading, measurement, and text wrapping.
    • <ttypt/lam-tm.h> — Sprite tilemap subdivision and batch 2D map grid rendering.
    • <ttypt/lam-key.h> — Hardware keyboard event codes, gamepad buttons, and directional hats.
  • Canonical lam_* symbols across lifecycle (lam_init, lam_size, lam_flush, lam_poll), primitives (lam_fill, lam_clear, lam_rect, lam_line), and textures (lam_tex_*).
  • Typed color packing and unpacking helpers: LAM_RGBA(r, g, b, a), LAM_RGB(r, g, b), channel extractors (LAM_COLOR_R/G/B/A), and standard palette constants (LAM_COLOR_WHITE, LAM_COLOR_BLACK, LAM_COLOR_RED, LAM_COLOR_GREEN, LAM_COLOR_BLUE, LAM_COLOR_YELLOW, LAM_COLOR_CYAN, LAM_COLOR_MAGENTA, LAM_COLOR_TRANSPARENT).

• Flexbox UI Engine (lam_ui_*):

  • Declarative container constructors: lam_ui_flex(parent, dir), lam_ui_box(parent, w, h, bg_color), lam_ui_label(parent, text, font_ref, color).
  • Direct style setters: lam_ui_set_size, lam_ui_set_bg, lam_ui_set_padding, lam_ui_set_flex, lam_ui_set_align.
  • Full CSS flexbox semantics: LAM_UI_ROW, LAM_UI_COLUMN, LAM_UI_JUSTIFY_*, LAM_UI_ALIGN_*, padding, borders, drop shadows (lam_box_shadow), and rounded corners (lam_border_radius).
  • High-performance layout cache powered by libcorm for sub-millisecond layout reuse.

• Sprite Tilemaps & Font Atlases:

  • Pre-rendered bitmap font atlases (lam_font_open, lam_font_draw, lam_font_measure) with word wrapping and vertical overflow inspection.
  • Subdivided sprite atlases (lam_tm_new, lam_tm_get, lam_tile_draw) and batch grid map blitter (lam_tile_map_draw).

• Engine & Driver Bug Fixes:

  • Registered cm_gl_tex in libcorm (corm_reg), resolving corrupted texture descriptor lookups and eliminating vertical line rendering artifacts.
  • Corrected presentation shader UV orientation (VS_PRESENT) to ensure right-side up display.
  • Unified texture uploading on GL_RGBA with GL_CLAMP_TO_EDGE wrap modes.
  • Added Core Profile GLEW initialization fallback for headless environments.
